Hi all,

I have added protective groups ACE and NME to my protein. I want to relax
them. My first residue in the protein is ACE.

When I do

a=loadpdb protein.pdb
select a.1
relax selection

It gives me the error

!FATAL ERROR----------------------------------------
!FATAL: In file [list.c], line 437
!FATAL: Message: llListLoop called with NULL list

Could anybody please tell me why it says that it is a null list? Coz I know
for sure residue number 1 is ACE.

Thank you in advance
