InPut Para -Region chromosome [contig] can't be found in the SNP dataset

[Jokendo-collab]

I am getting the above error even though the region is present in my data. What could be wrong?

It is recommended that you change the chr name in your vcf from contig-0030316_TU to contig_0030316_TU.
gzip -d *vcf.gz ; sed -i '/contig-/contig_/g' *.vcf

This suggestion worked after changing the names. I also changed the contig names in my GFF file but when I pass my gff file I do not get gene names highlihted on my plot. I used the following command ./LDBlockShow-1.40/bin/LDBlockShow -InVCF merged_top_contigs.vcf -OutPut out_wik -Region contig_0023241_WIK:405598-14885150 -OutPng -InGFF top_contigs.gff

Because the region you gave is too large, so the gene length is too small and it looks like just a solid line when drawn, so by default, genes with more than 30 are not drawn. You can adjust this parameter ./ShowLDSVG -GeneLimtNum 100

./LDBlockShow-1.40/bin/ShowLDSVG -InPreFix out_wik -OutPng -InGFF top_contigs.gff -GeneLimtNum 100 -OutPut outFig
