Hi,
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
Created: Mon Mar 2 19:47:01 2020 (UTC)
Filesize: 2.8 KB
Dbkey:?
Format:data_manager_json
Standard error:

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;
- SAM indexer.
- Picard Indexer.
- 2bit (twoBit) indexer.
Any suggestions/help will be greatly appreciated.
Many thanks,
Steven.
