No outputs

[Lin-Yuying]

Hi there,

I encountered an issue recently when using dng-call function in DenovoGear v1.1.1 with command line
dng-call -f /home/ref/ref.fa -q 30 -Q 30 --ped FR24.ped P271.mark_duplicates.bam P433.mark_duplicates.bam P444.mark_duplicates.bam ...P452.mark_duplicates.bam -o test.vcf and also tried dng-call -f /home/ref/ref.fa -q 30 -Q 30 --ped family.ped -s family.samfiles -o test.vcf . However, there are no output in vcf files in all my analysis, except the header.

My family ped files looks like this:

##PEDNG v1.0
#individual Father Mother Sex Samples
P271 .    .    male =
P433 .    .    female =
P444 P271 P433 male =
P445 P271 P433 male =
P455 P271 P433 male =
P456 P271 P433 male =
P461 P271 P433 male =
P436 P271 P433 female =
P437 P271 P433 female =
P438 P271 P433 female =
P450 P271 P433 female =
P452 P271 P433 female =

The header in vcf files look like this

Could you help with this? Thanks in advance.

Can you check to see if this issues persists with the develop branch?

Hi Reed,

Thanks for your reply. I actually used the Mac version of DenovoGear, and cannot find any branch in the directory. Could you please provide more details of this kind of error?
Thanks!

Lin

The source code for the develop branch can be downloaded from here: https://github.com/ultimatesource/denovogear/archive/refs/heads/develop.zip

I suspect that if you aren't getting any out that your read group information in your bam files do not match the information in your pedigree file.

Hi there,

I solved this issue by replacing '=' with samples names in family ped files.
