Dear Carnival Developers,
First, thank you for the great tool, it really is amazing.

My issue, now, is trying to run Carnival in parallel, but that is not working. I made a toy example to run it but it is not working.

library(furrr)
plan(multisession, workers = 4)
library(CARNIVAL)

load(file = system.file("toy_inputs_ex1.RData",
                        package="CARNIVAL"))
load(file = system.file("toy_measurements_ex1.RData",
                        package="CARNIVAL"))
load(file = system.file("toy_network_ex1.RData",
                        package="CARNIVAL"))


input_lists <- rep(list(toy_inputs_ex1),times=20)
meas_lists <- rep(list(toy_measurements_ex1),times=20)
net_lists <- rep(list(toy_inputs_ex1),times=20)
input_lists <- rep(list(toy_inputs_ex1),times=20)

result = future_map(input_lists, function(lst){
  runCARNIVAL(inputObj = lst, measObj = toy_measurements_ex1, threads =1,
              netObj = toy_network_ex1, solverPath = "/usr/bin/cbc", solver = "cbc")
})

This is the error that I get when running it.

Solving LP problem...
Error: 'results_cbc_1_1.txt' does not exist in current working directory ('/home/ahmed/Comp_Bio/Projects/Discovery_Pipeline').
In addition: Warning message:
UNRELIABLE VALUE: Future (‘<none>’) unexpectedly generated random numbers without specifying argument 'seed'. There is a risk that those random numbers are not statistically sound and the overall results might be invalid. To fix this, specify 'seed=TRUE'. This ensures that proper, parallel-safe random numbers are produced via the L'Ecuyer-CMRG method. To disable this check, use 'seed=NULL', or set option 'future.rng.onMisuse' to "ignore".

I looked at the one of the development branches, and it seems that this was somehow addressed with parallelIdx1, but it always has a fixed value of 1 and there is no argument in the runCarnival function to change 'condition' that would then send off different arguments to the cbc solver instead of always looking for the 'results_cbc_1_1.txt' file which is already in use by the first node.

Thanks,

Dear respectful developers,

May I apply for your guidance at your convenient time about runCARNIVAL step?

When using the latest version cplex and VARNIVAL and R4.1.3, in the runCARNIVAL step, it saved the lp file, and then shows Error in file(file, "rt"): cannot open the connection, and cplex seems not generate the results file in the working directory as expected.

Thanks a lot! Much Appreicate!

When I put progeny pathway score (dataframe, 1obs. of 14 variables) into runCARNIVAL function as weightObj, I got the following error message.
"Error in if (nrow(weightObj) != nrow(measObj)) "

However, my weightObj (dataframe, 1obs. of 14 variables) and measObj (dataframe, 1obs. of 289 variables) have the same number of row.

If you provide example pipeline using progeny pathway score as weightObj, it will be very helpful.

R version 4.0.2 (2020-06-22)
CARNIVAL version 1.0.0

Using BigSur 11.6 and CPLEX 20.10, I get no DOT figure with CARNIVAL 2.2 as an output network even though the problem is optimal. The same inputs generate a DOT figure file in Windows10 as normal.

For my project I read your paper with the title "From expression footprints to causal pathways: contextualizing large signaling networks with CARNIVAL '' and it was really interesting to me, the procedure you applied in different stages was novel and clever. Just some questions remained in my mind and I really appreciate you helping me to answer them: first: what was your request from Omnipath Db to create your PKN network, I downloaded it from Omnipath Db with the following code but I got more interaction than you mentioned in the paper, Can I ask you to send your script for me?
My code:
interactions <-import_omnipath_interactions(resources=c("SignaLink3","PhosphoSite","SIGNOR"))
Secondly:
As you mentioned in the paper we can use PROGENy tools for pathway activity but I don't understand which format is acceptable? I read your vignette but unfortunately, I didn't find any related data to see what should be this input?
Finally: is it possible for you to send me a real example R script that you run on CARNAVAL? I ran your toy example but for more understanding about its real application, I need a true one.
I hope you help me to answer my questions.
Best Regards

The supplied "progenyMembers.RData" file contains only the human genes used in the progeny pre-steps. One with mouse genes would be required to be compatible with mouse input.

So there is no need to rerun from scratch

checkMeasObj removes nodes that are not in the networkObj but does not notify the user.

Hi,
it seems to me that gurobi is already part of this version (can be selected as solver), but there is no documentation about which parameters can/should be used in ?runCARNIVAL(). Is it described somewhere or could you add it to runCARNIVAL?
thanks
Attila

Dear @ivanovaos
as we discussed in this issue #61, I would suggest that we add two additional options to be sent to the CBC solver command line.
Those would be: threads and randomseed , which would help speed up CBC that was built with support for multithreading by adding that option to the config file ./configure --enable-cbc-parallel
Many thanks!!
Ahmed

Hey,
the following dependencies should be revised:
Imports:
doParallel, --- is it compulsory?
readr, (? not sure if really needed)
viper, -- (do we need Dorothea for CARNIVAL? or is it only used for the vignette?)
AnnotationDbi, -- gene name mapping should be done outside carnival, right?
UniProt.ws, -- gene name mapping should be done outside carnival, right?

Converting adj from sparse to dense matrix is leading to memory issues on larger problems (>30000 nodes/reactions take up more than 8 Gb).

Since this variable is only needed to identify which rows sum up to 0, line 21 could be removed and this line below could probably replace the idx1 definition, although this is not as efficient as it could be.

idx1 <- where(sapply(1:dim(adj)[1], function(x){sum(adj[x,])}) == 0)

I would expect that solely providing solverPath would be enough to change from default lpSolve.

Review the code part that does it and find optimisations

Hi,

it seems the command vignette("CARNIVAL-vignette") leads to a warning:

vignette ‘CARNIVAL-vignette’ not found

I tried the Bioconductor and the github version but neither versions contain the vignette. Can you fix this?

I'm running CARNIVAL v 1.0.0 on R4.0.1.

Many thanks,
Axel

Hi,

Is any method of speed up the analysis in carnival?

• Would you suggest the best speed solver? (cbc or cplex)

• multi-processing/threading or anything

Thank you in advance!

(In my case, there are about 20,000 genes and 171 samples)

Tried to rerun some code written just a couple of weeks ago. Getting this error now when generating the measurement file.

I noticed that the folderpath variable is declared inside the generate_measfile() function but not defined.

Moreover, I cannot find the generate_measfile() in the source code you currently have available. Have you changed the name or otherwise?

I pasted my error below:

> generate_measfile(measurements = TF_uniprot, \+ topnumber = NULL, \+ write2folder = "measurements") Error in paste0(folderpath, "/meas_", drug, "_all.txt") : object 'folderpath' not found

https://github.com/saezlab/CARNIVAL/blob/master/R/exportResultCPLEX.R

reports matrix sometimes or a string other times (if all nodes are 0) -- this is bad practice and can mess up downstream.
It should return a matrix with zero row.

for the parallel runs

Hey Saezlab:)

I found an error in progenyMembers.RData: The p53 pathway is mapped to "P53" in the file, but in Omnipath it is called "TP53".

As consequence, I've been getting this warning:
These nodes are not in prior knowledge network and will be ignored: P53

This might have been simply my mistake back in the days, but if it is due to updates in gene name conventions this might be something to look out for more generally?

All the best,
Anika

Hello,

I am interest in running CARNIVAL on multiple conditions data.

I have found a branch in which this aspect was investigated, however unsure whether is the most suitable way to perform this task.

https://github.com/saezlab/CARNIVAL/tree/multiple_conditions_carnival

I would appreciate if you have any suggestions in this respect.

Hi,

I am running CARNIVAL using saezlab/transcriptutorial. I tried using IBM cplex but it didn't work out and I kept getting this:

Error in resList[[1]] : subscript out of bounds
In addition: Warning messages:

Finally, I installed lpSolve in R & made a ~/.Renviron file with R_MAX_VSIZE=100Gb & removed unused variable from the environment. And I got this one:

Dear all,
I have some problems saving the outputs of runCARNIVAL() , e.g. weighted_Model.txt, nodesAttribute.txt. etc. These files are just not saved, they appear nowhere on my computer. The only thing being saved when running the function is the DOT-figure.
I have already tried giving an absolute path and just the directory (as input for 'dir_name'), and with and without DOTfigure saving.
Do you have an idea what could be the reason?

Oh hai!
When running runCARNIVAL, the following error message is thrown:

And the warning:

Can anyone help to solve this issue?

Dear All,
I noticed that you changed the prerequisit R version in the description file to >=4.0. This stops Carnival installation for R 3.6.3 which was released 6 weeks ago. Could you decrease that to 3.5?
Kind regards,

Hi, I'd like to use this software for my research. Although I I can't find a complete tutorial or an example (including Dorothea and Progeny) through which I can understand the pipeline. I have a set of target perturbations and a gene expression matrix. How can I get the final signaling network ?

Add processing of results when the list is empty.

Hi,

I really liked trying CARNIVAL for my project! For more advanced network visualization, I need to know details of the output list. Could you please provide that information especially for weightedSIF and nodesAttributes? In specific, I have only "T" and NA node type. T is equal to 100 AvgAct, while NA node type could be -100 or 0. What would that mean?

I do not get this issue with the toy example 1.

I tried adjusting threads (we have 40 in total which are all free atm), timelimit (300 to 6000), solver (Cplex or the free solver). I think it is a memory issue but I am not entirely sure how to rectify it. For network I am just using the Omnipath network, so nothing too huge. Default no. TFs and then the PROGENy pathways as input. The run_carnival.R script I am using can be found here https://github.com/laylagerami/EPA/tree/main/Initial_Investigation/Scripts which also has all of the input files etc.

Thanks!

EDIT: .lp file is here https://github.com/laylagerami/EPA/blob/main/Initial_Investigation/Scripts/testFile_1_1.lp

Hello,

I am having some issues understanding the inputs for the CARNIVAL program.

1). measFile : I get a matrix (Transcrition Factors as rows and Samples as columns) from DOROTHEA after using run_viper on gene expression matrix and . But the input to CARNIVAL has two rows: the TFs and the values. Should I take an average for the TF-activity across samples (or Median) to get a two row format ?

2. weightFile: Similar is the case for the PROGENY output. Can I again take average(or Median) across samples for the pathway scores as well ?

3. inputFile: Can I use the sign fold change of differential gene expression to construct this file ? As in -1 for the down-regulated genes and 1 for upregulated genes ...

Thanks in advance for any help.

Anupam

Hi,
Thanks for developing this great tool, I have one question and your answer is really helpful for me,
Question: I want to run CARNIVAL on a single cell dataset and it contains more than 300 cancer cells, I should run CARNIVAL on each cell separately? because in your transcriptutorial you run it on a for loop.
Thanks in advance

From create_lp_formulation.R, functioncreateGenerals_v2 :

generals <- paste(c(variables$nodesDf$nodesVars,
                      variables$nodesDf$nodesActStateVars,
                      variables$measurementsDf$absDifference), sep="\t")

Hello all. Thanks a lot for putting up such fantastic work!

Very sorry for this non-error issue but I wonder if variables$measurementsDf$absDifference here should be variables$measurementsDf$value instead? There is no error running the pipeline like this though.

Having tried this part of the code, I also realised the two values from the toy_measurements_ex1.RData were not written down at the end of the Generals in the toy_lp_file_ex1.lp file. Should it be like this? Or is it because those values happen to be 1 so when writing output, it just writes two \t?

Thanks a lot.

Me again...

I can't get cbc solver to work. Not sure if it isn't generating results due to the nature of the error message, but it still says "Result - Optimal solution found". Have tried with InvCarnival only for now, with two different data inputs (both of which worked w/ Cplex) and a toy example.

The error message is below - the output starts with the usual text and then continually outputs the solving process as expected, then ends with:

Hi,
could we please update the bioconductor package with the constraint fix commits? (if this version passes all the requirements/test the the current version would be also ok, i guess)

Hello,

I was running CARNIVAL on a case study and I got an error when cplex was about to solve the ilp problem introduced. The issue was that some of the identifiers had an undesired "-" symbol on it (i.e. genes NKX2-1, NKX3-1, etc.). These symbols are recognised as a minus in the problem formulation and might cause problems. Please be careful with the names of the protein identifiers introduced in the PPI, input or measurement files and not add any mathematical symbol on them.

Cheers,

Hi devs,

I have noticed that I am getting very different results with CARNIVAL now compared to the previous version. I am using the exact same OS, cplex version, input data and settings (default w/ 20 cores).

Specifically, before the network I obtained had 69 nodes and 140 edges. Running with the new version of CARNIVAL, the weighted network now has 2535 nodes and 7672 edges. This is quite large since I would like to visualise the network in a Shiny app! Is this behaviour intentional?

I also tried running a different dataset with both cbc+cplex and again obtained very big networks compared to what I was getting before, but haven't got an exact "before" to compare to.

Let me know if you need anything else from my side to understand what's going on,

There is an unhandled error occuring in some cases:
Error in resList[[1]] : subscript out of bounds Calls: ... <Anonymous> -> solveCARNIVAL -> solveCARNIVALSingle

Implement a CPLEX log parser in the execution time of runCARNIVAL()

Suggested by Martin

I have realized that some times runCARNIVAL founds solutions, but the pipeline retrieves "No result to be written", without giving any error/warning message.

I have dug in the code, and I have found that it puts together current_dir and dir_name. current_dir gets the current working directory, and if the dir_name is an absolute path, then you can end up with a nested path that doesn't exist. Due to this conflict, even if there are solutions to be generated, they are never written.

Be aware that the argument for Result_dir must NOT be an absolute path.

optimal function value - size penalty = goodness of fit

There was an issue with assigning the order of activity values for the inputs. This issue occurs only when there is a combination of positive (1) and negative (-1) values in the same set of inputs.

the formatting of node names are done independently for network (controlNodeIdentifiers) , inputs (checkInputObj) and measurements (checkMeasObj).
This should be handled by the same function, if possible, to assure they are done the same way.
