I am trying to filter a vcf file Info column. I have some Info Fields with values "DP=.". When I try to use GATK VariationFilter tool with option
-filter "DP>50", it throws error: java.lang.NumberFormatException for input string ".". This is the case with many other values in INFO Column in vcf file. I also tried using
-filter "DP!='.' && DP>50". How can I overcome this issue?
