VCF info field code description

[lre1234]

Hi all,
I have made some SNP calls using Samtools, following the SNP calling, using the BCFtools, I have been playing around with some different parameters to see what I get. Once test that I tried used the following parameters:

bcftools view -vcgL -p 0.1

I tried this as I am not quite sure what the "-L" flag does. But, I got some info fields in the output which are not in the info definitions at the beginning of the file. Here is an example of 1 line of output:


chr1 888659 . T C 999 . DP=594;VDB=3.080559e-04;RPB=9.431136e-01;AF1=0.9444;AC1=17;DP4=11,52,145,376;MQ=48;FQ=999;PV4=0.097,1,1.4e-07,1;NEIR=1.000;NEIF4=0.944,0.000,0.000,0.056 GT:PLP:SP:GQ 1/1:255,178,0:59:0:99 1/1:255,163,0:54:0:99 1/1:255,148,0:49:0:99 1/1:255,152,0:64:0:99 1/1:255,157,0:52:0:99 0/1:255,0,255:100:5:99 1/1:255,114,0:38:0:99 1/1:255,253,0:84:0:99 1/1:255,231,0:84:0:99

My question is what are the "NEIR" and "NEIF4" (highlighted in red) info codes and how are they interpreted?

Thanks for any help.
