Fatal error: Exit code 1 () when using SAM FASTA Index Builder.


I am relatively new to using Galaxy, and I am attempting to try to eventually align my paired RNAseq data using STAR. I am currently running Galaxy (version 19.09) from a personal computer using a University open local server. I have successfully used the tool ‘Create DBKey and Reference Genome’ using the existing DBkey assigned as Mouse Dec. 2011 (GRCm38/mm10) (mm10) sourced from UCSC (with mm10 inputted into the field of ‘UCSC’s DBKEY for source FASTA’).

However, I have now come across a Fatal error: Exit code 1 () when I have tried to use the data_manager_sam_fasta _Index_builder tool using the DBKey I have created from the previous step (i.e mm10). The Dataset Information and standard error generated by the tool is below;

Dataset information:

Name: SAM FASTA index

There is most likely something really simple in which I am doing wrong, but I can’t seem to find any suggestions in previous forums which can solve this issue.

I am hoping to eventually follow previous guides of indexing this reference genome prior to using the STAR alignment tool on my server using Data Manager tools listed in sequence below;

  1. SAM indexer.
  2. Picard Indexer.
  3. 2bit (twoBit) indexer.

Any suggestions/help will be greatly appreciated.

Many thanks,

I don’t know much about this tool or method but look at the error.

Does not look like a fasta file to me. It are multiple file paths that are separated by a comma. Maybe you know where this comes from.

Yup, the entries in all_fasta.loc are wrong, this can happen when running the data manager multiple times for the same dbkey.
