I have a pdb file like this
ATOM 5 CB HIS 3 -16.235 -1.096 -33.335 1.00 93.62 57
POC
ATOM 6 CG HIS 3 -16.801 -2.279 -34.053 1.00 96.09 57
POC
ATOM 7 ND1 HIS 3 -16.128 -3.477 -34.152 1.00 97.72 57
POC
ATOM 34 OE2 GLU 6 -14.184 5.483 -27.224 1.00 74.34 44
POC
ATOM 36 CA VAL 7 -20.215 0.594 -25.878 1.00 54.93 20
POC
ATOM 40 CG1 VAL 7 -22.049 1.281 -24.309 1.00 53.91 20
POC
ATOM 40 CG1 VAL 7 -22.049 1.281 -24.309 1.00 53.91 67
POC
ATOM 46 CB ALA 8 -21.668 -2.539 -29.245 1.00 43.10 57
POC

I wonder if I can select the group of atms based on the number difference
of the next to the last collum.
Thanks!
