I assume you mean fastq files? See Cell Ranger, alevin-fry, or STARsolo documentation.
i am using starsolo on galaxy but i am getting the following error
EXITING because of FATAL ERROR in input read file: the total length of barcode sequence is 100 not equal to expected 28 Read ID=>SRR2431431.1 ; Sequence=ACTTAAAGGAATGTGGGCTTTATTGAGAGGATGGCATAGTAAAAGCTATTACAGGGAGGAGTGTTGAGACCAGATGTCATCTACTGTCTCTTGGGTCAGC SOLUTION: check the formatting of input read files. If UMI+CB length is not equal to the barcode read length, specify barcode read length with --soloBarcodeReadLength To avoid checking of barcode read length, specify --soloBarcodeReadLength 0
Does it mean that the RNA seq data is not 10x Chromium ? How to solve this error ?
for reference i am using E-GEOD-73121 dataset, and working with single cell rna seq of patients metastatic samples only
