Hi @RenaeAtkinson, Thank you for using Scasa in your research. The error is at the mapping step of alevin, likely it can not find out the input fastq files. Please check if the file names if they are in the right format. It is noted that the names of fastq files should contain "R1" and "R2", please see the details here: https://github.com/eudoraleer/scasa/wiki#6-input-fastq-files Best, |

hi @RenaeAtkinson, I don't see a clear issue in your command except "--project" instead of "–project". Most default values parameters are used in your command, so can you try again with the shorter version below: scasa --in /network/rit/lab/conklinlab/Renae/HNVC/HNVC02/SRR10340946/ Best, |

Hi, Can you try to test the issue by renaming SRR10340946_R1.fastq by Sample_01_S1_L001_R1_001.fastq and SRR10340946_R2.fastq by Sample_01_S1_L001_R2_001.fastq as in the sample files of Scasa Another possibility is that R1 and R2 files do not contain the correct information (one for sequence content and another for barcode+UMI), in that case we just switch the file name. Let try and please let me know if any of these ways work, thanks! Nghia |
I had tried that naming convention before and that did not work.
The names are according to the split files downloaded from SRA

Hi,
The error indicates that the alignment by Alevin has not been performed.
I am thinking of the reason that the input filename is not correct, but it is so weird because likely it is not.
Can you try to test the issue by renaming SRR10340946_R1.fastq by Sample_01_S1_L001_R1_001.fastq and SRR10340946_R2.fastq by Sample_01_S1_L001_R2_001.fastq as in the sample files of Scasa
Another possibility is that R1 and R2 files do not contain the correct information (one for sequence content and another for barcode+UMI), in that case we just switch the file name.
Let try and please let me know if any of these ways work, thanks!

Hi, It is really strange. Can you put the few first lines of R1 and R2 here? Nghia |
Sure thing,
It’s from a publicly available dataset and the sample I am working on is this SRA fastq file: https://www.ncbi.nlm.nih.gov/sra/?term=SRR10340946

Hi,
It is really strange. Can you put the few first lines of R1 and R2 here?
And if possible, can you send me the files or a subset of reads from the files, I will try to reproduce the error by running Scasa on the files.

hi @RenaeAtkinson , Well, I can not reproduce your error, please see the codes I tried below. So it is sure that the issue is not at the input data format. I guess you might have missed some steps, for example forgetting to add the paths of scasa or salmon alevin( export PATH and export LD_LIBRARY_PATH) Nghia

Hi Nghia,
I was trying to read in a particular file format but the format of the file did not match the format requested in the R function (of a different package). I will have to process the file in R to get it into the format required by the R function for it to be accepted. I got the same error in R that I saw in the command line when running SCASA! Error in file(con, "r") : cannot open the connection
In addition: Warning message:
In file(con, "r") :
cannot open file 'C:\Users\renae\Desktop\Rprojects\SingleCellar-Learn\Human_genesets\Human_genesets\human.signature.genes.v2.gmt': No such file or directory
I am excited because now I know what the error with scasa meant. It meant that the R function was not able to process the file provided into the format that scasa requires and so produced the error. The error occurs at “Begin scasa quantification for sample SRR..”. Does that shed any light on what could be going on and how you could help me?
I would really love it this could work. What you produced in your paper is exactly what I want.

Hi @RenaeAtkinson, If you see the message: 'Error in file(con, "r") : cannot open the connection', it is definitely that the program can not find out the file and so it is not the issue of Scasa. I have tried to run Scasa with your working sample SRR10340946 on my linux computer, it worked well without error. I have provided you the codes previously (but I forgot to put them in the code format, very sorry). So I put the codes again below. I use the sratools to download SRR10340946 data. You just need to copy-and-paste the command lines and it should work. Nghia

Hi Nghia,
So I use salmon in a conda environment on my Linux server. I just updated it to through conda. I have version 1.10.1. I did everything including redownloading the sra file. The first error I get is this:
mkdir: cannot create directory ‘ScasaOut_SRR10340946/SCASA_My_Project_20230518140856/’: File exists
Is this a problem with scasa?
The second error I get is
Error in file(con, "r") : cannot open the connection
Calls: readLines -> file
In addition: Warning message:
In file(con, "r") :
cannot open file 'ScasaOut_SRR10340946/SCASA_My_Project_20230518140856/1ALIGN//SRR10340946_L001_alignout/alevin/bfh.txt': No such file or directory
Execution halted
This suggests to me that the program is having a problem making the directory/file bfh.txt.
A similar error emerged later
In readChar(con, 5L, useBytes = TRUE) :
cannot open compressed file 'ScasaOut_SRR10340946/SCASA_My_Project_20230518140856/2QUANT//SRR10340946_L001_quant//scasa_isoform_expression.RData', probable reason 'No such file or directory'
Execution halted
Any ideas what could be the issue? Am I the only person having this problem?
