snpEff error when connecting to my built database
I am trying to built a database, called Tre1. I used the sequences.fa and genes.gtf stored in snpEff/data/Tre1. I assume the database was built properly as I followed the instructions in snpEff website.
And when I try to annotate SNPs in snpEff/vcfs with the following command:
java -Xmx8g -jar snpEff.jar Tre1 vcfs/21.filtered_snps_final.vcf > 21.anno.vcf
the error comes out like this:
00:00:00 ERROR while connecting to https://snpeff.blob.core.windows.net/databases/v5_1/snpEff_v5_1_Tre1.zip
00:00:00 ERROR while connecting to https://snpeff.blob.core.windows.net/databases/v5_0/snpEff_v5_0_Tre1.zip
FATAL ERROR: Failed to download database from [https://snpeff.blob.core.windows.net/databases/v5_1/snpEff_v5_1_Tre1.zip, https://snpeff.blob.core.windows.net/databases/v5_0/snpEff_v5_0_Tre1.zip]
What might be the problem? Did I not build the database successfully?

snpEff database error

It would be best to check the log files rather than assuming it was done correctly. Looks like snpEff is trying to connect to a remote location for the files yet you said you built a custom database locally.
I am very sorry, I wasnt aware of that. Just new to bioinformatics and this page.
Nothing to be sorry about. All part of learning. Did you follow the steps here: https://pcingola.github.io/SnpEff/se_buildingdb/#building-a-database Were there any log files produced when you built the database? Have you checked those to see if there were any errors.
Yes i followed all the steps there. And ya u are right, the database were not built, cus i didn't see any log files produced. I think I am missing CDS and protein sequences so I got errors like Error in CDS and protein check... I thought gtf and fa files were the only ones required at first....
Do i need to extract CDS and protein sequences from the genome annotation file in GTF format?
Step 2 should need just GTF. You will need to provide CDS in step 3 where it checks your database against that information. Are you using a custom genome or one that is available some place like NCBI.
I am using a custom genome
