hi I am trying to do the bilayer analysis and want to calculate order parameters using g_order. I made the index using make_ndx command and selected the carbons sai 1-16 of my first chain and 17-33 of the other in same index file as two separate group. When I am giving this index file to g_order I get the error:
Using following groups: Groupname: System First atomname: C1 First atomnr 0 Groupname: POPC First atomname: C1 First atomnr 0 Groupname: SOL First atomname: OW First atomnr 6656 Groupname: oleoyl First atomname: C1 First atomnr 1820 Groupname: palmitoyl First atomname: C1 First atomnr 832 Reading frame 0 time 0.000 Number of elements in first group: 14036 ------------------------------------------------------- Program g_order, VERSION 3.3 Source code file: gmx_order.c, line: 160 Fatal error: grp 1 does not have same number of elements as grp 1 Please help. _________________________________________________________________ Tried the new MSN Messenger?
