[ensembl-dev] VEP version 73 fasta file error

Hi Will,

Sorted it, I solved the problem by deleting the index to the v73 FASTA file and therefore forcing VEP to recreate the index. This in turn resolved the problem.

Thanks again,
David

I can't recreate the problem; I'm using API v73, VEP 73, the 73 main cache (NOT RefSeq) and the same 73 FASTA file you describe.

My output:

> perl variant_effect_predictor.pl<http://variant_effect_predictor.pl> -i duarte.vcf -offline -force -hgvs -fasta /[path]/73/Homo_sapiens.GRCh37.73.dna.primary_assembly.fa

I get no warning messages, only the usual output.

Are you using any other options besides those described in your config file?

Are you using the RefSeq cache, or the default human one?

Dear Will

David works with me...  Here is an example line where this is happening:

Hi David,

Are you able to provide a line or more of input that recreates the issue?

This would help greatly with debugging the problem.

Dear Developers,

I am running version 73 of the VEP script and API. I am running the script in offline mode, cache only with the HGVS option selected and a fastq file specified (see snippet from config below):

#######     cache stuff   #############

when running the program I get the following warning (with trace, some line numbers may have changed in my vep script due to adding the libs for the modules):

Could you please shed some light on what is going on? I have not yet figured out if this warning has any effect on the output.

Many thanks,
