[gmx-users] g_cluster fatal error

[Louis Lategan Du Preez]

Hello

I am trying to cluster an extremely large trajectory (about 550 ns) with g_cluster and i get the following fatal error from g_cluster:

Program g_cluster, VERSION 4.5.1
Source code file: matio.c, line: 943

Fatal error:

The command-line options i used were:

Please help
