[gmx-users] g_helix issue

[Ming Tang]

Dear all,

I am using gromos54a7 ff to simulate a triple helix. When using g_helix to get some of the basic properties, I got the following error:

Program g_helix, VERSION 5.0.4
Source code file: /home/tm/Downloads/gromacs/src/gromacs/gmxana/hxprops.c, line: 437

Fatal error:
Zero complete backbone residues were found, cannot proceed
For more information and tips for troubleshooting, please check the GROMACS

Could anybody tell me how to fix this problem?

Thanks.
