Quantification Fails

[abhideeplife]

Hi,

Thank you for the tool. I am using it for isoform quantification. As a test run I am testing it on one sample from 10xV2.

The command that I am using

scasa --fastq ERX3806131/4861STDY7462259_R1.fastq.gz,ERX3806131/4861STDY7462259_R2.fastq.gz --ref $refPath --nthreads 8 --out Scasa_out

Processing message that I get

I have installed all the R packages and I am not sure why the quantification is not being performed.

Could you please help.

Thank you
