Hi
No errors reported, but the group file (xxx.shhh.groups) does not contain a second column where the group is specified
eg:
H4PQ3VT01ACOJY
H4PQ3VT01DWUSW
H4PQ3VT01C3AR6
H4PQ3VT01DTTDP
H4PQ3VT01A2XJE
Tried it, same version on linux and that worked:
H4PQ3VT01ACOJY M2_1
H4PQ3VT01DWUSW M2_1
H4PQ3VT01C3AR6 M2_1
H4PQ3VT01DTTDP M2_1
H4PQ3VT01A2XJE M2_1
Cheers
Erik
