Enrichmentmap combine datasets from R about enrichmentmapapp HOT 8 CLOSED

You can merge networks in Cytoscape using the merge tools but for use case much better to create a mastermap with all the EM features. An Enrichment map from multiple datasets. In order to automate it you have set up a directory structure where each dataset is in its own directory. EM will take the names of the directory as the name of the dataset.
For example
mastermap_dir
Dataset1
generic_EM_results_Dataset1.txt
Dataset2
generic_EM_results_Dataset2.txt
Dataset3
generic_EM_results_Dataset1.txt

Then when you are creating the enrichment map mastermap instead of specifying the individual files you specify the root directory and EM will be able to find all the datasets.

em_command = paste('enrichmentmap mastermap ',
'pvalue=',"0.5", 'qvalue=',"0.5",
'similaritycutoff=',"0.25",
'coeffecients=',"JACCARD",
'rootFolder=',egobp.results.dirname ,
sep=" ")

Thanks for the quick reply. I am getting this error when I am running it:
Error: Error: no such command: 'mastermap '

Do I need to call the directory in a specific way?
I am running Cytoscape on Version: 3.9.1 and RCy3_2.10.2 .

What version of enrichment map do you have? (I think it would have be a really old version of enrichment map to not have mastermap.)

In cytoscape, in the command line window when you run "help enrichmentmap" is there a "enrichmentmap mastermap" listed?

I fixed it with removing space after mastermap, also had to remove the coefficient term, as it was giving error. But this worked:

em_command = paste('enrichmentmap mastermap',
'pvalue=',"0.5", 'qvalue=',"0.5",
'similaritycutoff=',"0.25",
'rootFolder=',egobp.results.dirname ,
sep=" ")

mastermap's parameters only allow the correctly spelled coefficients but the build command because of a spelling mistake a long time ago accepts coeffecients and coefficients. If you change the parameter in your mastermap command to coefficients it should work.
I am not sure why the space gave you issues though.

Yes, that works. Thanks.
Btw, is there a way to show only the p value pie charts but not the names of the pathways? I have so many and I see them on top. I was trying to change the font, but didn't see how to do that.

Sorry. I forgot to respond to this when I first saw it.
Yes. You can suppress the labels. In EM there is a toggle button in the EM interface that hides the labels when you click "Publication ready" but unfortunately that is not available through the em commands. It might be an easy feature to add to the commands.
I think that all the feature is doing is setting the node labels to zero so you can also do that using RCy3 using the following command (but I am not sure that is still the way it is done) @mikekucera how does the publication ready work?:
