I am novice in using modeller.Thanks for your reply for my previous mail.

the file  /mod6v2/modlib/CHAINS_3.0_40_XN.GRP; has pdb codes in the
following format

1xnb : 1c5hA 1refA 1bvv 2bvvA 1xnd 1redA 1reeA 1xnb 1ukrA 1xnc 1xypA 1yna
1bk1 1xyn 1xyoA 1bcx 1enxA 1pvxA 1c5iA 1qh6A 1qh7A 1hv0A 1hv1A 1hixA 1hixB
1bpyA : 8icfA 8icvA 9icfA 9icvA 7icfA 7icvA 1zqfA 2bpfA 8icgA 8icwA 9icgA
9icwA 7icgA 1zqgA 2bpgA 8ictA 9ictA 7ictA 1zqdA 1zqtA 1bpd 8iceA 8icuA 9iceA

Doubts:

a)Why the PDB code 1xnb is seperated from the other PDB codes with a
colon.(:)
b)Why the pdb codes aren't listed continuously.Why are they listed on
seperate lines?

Thanks in advance
