[gmx-users] g_dist: Indexfile seem to be NOT optional

Hi GMXers,

according to the man page of g_dist, the -n option is optional. But when
I try to use g_dist without -n (and without an index.ndx in the working
directory), I get the following error:

Program g_dist, VERSION 4.0.5
Source code file: futil.c, line: 330

File input/output error:

Since the .tpr file has all information g_dist needs (and my .ndx files
are not on the single working nodes), I do not understand why this error

Just to make clear, that there is no other mistake: When using the same
command with -n and a valide index file, g_dist works fine.
