I am using bcftools to merge 5000+ vcf files using this command
bcftools merge -l list_of_vcfs.txt
I am getting the following error
Warning: The row size is too big for FORMAT/PL at chr1:23899810, requires 12204615120 bytes, skipping.
The REF prefixes differ: C vs N (1,1)
Failed to merge alleles at chr1:53128382 in <sample>.vcf.gz
Any help on how to fix this issue would be appreciated.
