cn_salmon Error: cannot open compressed file 'geneToTrans_Homo_sapiens.GRCh38.80.exo_Jul_04_2015.R' about cellnet HOT 5 OPEN

Hi,

Thanks for the interest in CellNet. geneToTrans_Homo_sapiens.GRCh38.80.exo_Jul_04_2015.R' is bundled as part of the index (e.g. salmon.index.mouse.052617.tgz) that is used in the pre-processing steps. Please let us know whether this addresses the problem.

Sorry, I still can't find 'geneToTrans_Homo_sapiens.GRCh38.80.exo_Jul_04_2015.R' in salmon.index.human.052617.tgz which I uncompressed. The compressed file contains the following content:
hash.bin header.json indexing.log quasi_index.log refInfo.json rsd.bin sa.bin txpInfo.bin versionInfo.json
And I noticed that versionInfo.json mentioned
{ "ReferenceFiles": [ "/media/ephemeral0/Homo_sapiens.GRCh38.cdna.ncrna.exo.Jul_05_2015.fa.gz" ] }
Does it mean I need to download the fa.gz file?

I locally ran CellNet in my lab's cluster, error occured as followed:
Error in readChar(con, 5L, useBytes = TRUE) : cannot open the connection In addition: Warning message: In readChar(con, 5L, useBytes = TRUE) : cannot open compressed file 'ref//geneToTrans_Homo_sapiens.GRCh38.80.exo_Jul_04_2015.R', probable reason 'No such file or directory'

Besides, I noticed the mapping rate=0%, detailed information exported by salmon as followed:

Wish I had clarified my problem for you.

Got same issue. Did you solve this problem?

from cellnet.

We have now created a web application that takes as input an expression matrix (counts, TPM, or FPKM), and sample meta-data, and performs CellNet analysis. Additionally, this tool includes analysis of many state-of-the-art differentiation protocols, so that you can benchmark your results against those commonly used methods:

I got same error. Was the problem solved?
