Hello,

I'm performing STARsolo on fastq files and I'm using the reference genome from 10X genomics but I have this issu that I can't understand (the reference genome is indexed)

STAR version: 2.7.10b   compiled: 2022-11-01T09:53:26-04:00 :/home/dobin/data/STAR/STARcode/STAR.master/source
Mar 13 14:42:48 ..... started STAR run
Mar 13 14:42:48 ..... loading genome
EXITING because of FATAL ERROR: Genome version: 20201 is INCOMPATIBLE with running STAR version: 2.7.10b
SOLUTION: please re-generate genome from scratch with running version of STAR, or with version: 2.7.4a
Mar 13 14:42:48 ...... FATAL ERROR, exiting

this is the command line that I'm using:

/opt/conda/envs/scRNA/bin/STAR \
  --genomeDir /lab/user/bricks/reference/refdata-gex-GRCh38-2020-A/star \
  --readFilesIn R2.fastq.gz R1.fast.gz
  --soloType CB_UMI_Simple \
  --soloCBwhitelist /cellranger-7.1.0/lib/python/cellranger/barcodes/737K-arc-v1.txt \
  --soloUMIlen 12 \
  --soloCBlen 16 \
  --soloUMIstart 17 \
  --soloFeatures GeneFull

thank for your answer but it was wird for me that he asks to do the indexation. Anyway I performed the indexation process but now I have this type of error

Your files are gzipped.

You need to add --readFilesCommand zcat
