Allows to keep or remove samples from a VCF file.

.. class:: infomark


**Example**:

Selecting *NA00001* and *NA00003* from the following VCF line::

 #CHROM POS     ID        REF ALT QUAL FILTER INFO                              FORMAT      NA00001        NA00002      NA00003
 20     1110696 rs6040355 A   G,T 67   PASS   NS=2;DP=10;AF=0.333,0.667;AA=T;DB GT:GQ:DP:HQ 1|2:21:6:23,27 2|1:2:0:18,2 2/2:35:4:.,.

will, obviously, remove *NA00002*::

 #CHROM POS     ID        REF ALT QUAL FILTER INFO                              FORMAT      NA00001        NA00003                                                  
 20     1110696 rs6040355 A   G,T 67   PASS   NS=2;DP=10;AF=0.333,0.667;AA=T;DB GT:GQ:DP:HQ 1|2:21:6:23,27 2/2:35:4:.,.

Vcfselectsamples is based on vcfkeepsamples/vcfremovesamples utilities from **VCFlib** toolkit developed by Erik Garrison (https://github.com/ekg/vcflib).
