Hello,

I'm trying to run your tool and can't get it to work. I was running in "already aligned" mode since salmon alevin has already been run. However it can't get beyond the below. These directories do not exist before executing the command.

scasa --postalign_dir salmon/ --align NO --quant NO --in cDNA/ --fastq test_R1.gz,test_R2.gz --ref reference/gencode.v34.transcripts.fa --out /mnt/disks/big_data/calico/scasa

All done!

Even on your tutorial example, there are similar errors, but it keeps going:

mkdir: cannot create directory ‘Scasa_out/SCASA_My_Project_20220321143943/’: File exists

Hi nchernia,

Thank you for submitting the question! Basically, Scasa is a quantification tool, if you set --align to NO and --quant to NO, which means no alignment will be done and no quantification will be done, i.e. you do not want scasa to do anything, so nothing would be done. Another thing is, for all the paths you need to provide, it has to be in full path, i.e. if you provide a path in the current directory for example, you need to specify from root, for example, a path to the fasta reference file: /mnt/example/new/reference_file_name.gz

I have fixed some bugs along the way, thank you for pointing out the error, could you mount scasa again and try again and let me know if if works?

Best,
Lu

Some of the R packages are needed for using Scasa, but it seems that the packages have no permission to get install in the default directory, another way is that, you could try installing the package dependencies before using scasa:

library(GenomicFeatures)
library(Biostrings)
library(polyester)
library(foreach)
library(doParallel)
library(data.table)
library(plyr)
