In previous releases, a combination of the chromosome name and the position at which the variant is located was used as the variant identifier. In this release, we kept it in case the variant ID is not in the VCF/BCF file. If the variant ID is listed in the VCF/BCF file, we saved it for further analysis. To do this, changes were made to the ps_pl2_pvar_edit.pl program, which is executed in the first script (pre_analysis_first_script.sh).
