Help with generating annotation database for dog genome to use in ANNOVAR for variant annotation of dog tumor sequences

Question

[sainavyav22]

Hello,

I am using ANNOVAR to perform variant annotation of my dog tumor reads. I am facing issues to generate the annotation data base. I have used the following protocol.

1. I have downloaded the dog genome annotation file in GFF format from NCBI database, then converted it into genePred file to generate dog_refGene.txt file.

2. I ran the following commands, that are provided in the annovar website to generate annotation database for other than human genome.

   perl annotate_variation.pl --buildver CanFam3.1 --downdb seq dogdb/CanFam3.1_seq -fastafile GCF_000002285.3_CanFam3.1_genomic.fna perl retrieve_seq_from_fasta.pl dogdb/CanFam3.1_refGene.txt -seqdir dogdb/CanFam3.1_seq -format refGene -outfile dogdb/CanFam3.1_refGeneMrna.fa -fastafile GCF_000002285.3_CanFam3.1_genomic.fna

There it is mentioned to run the both commands consequently. After running the first command I received the following warning message, and the second command is not running.

Can someone please help with this. How to generate the annotation database for genome to use in ANNOVAR or Is there any other annotation platforms for better annotation? Thanks.

the URL is

https://hgdownload.soe.ucsc.edu/goldenPath/canFam3/bigZips/

not

http://hgdownload.cse.ucsc.edu/goldenPath/CanFam3.1/bigZips/

you should look in those perl script where the URL to the UCSC is constructed
