[gmx-users] Converting Amber ASCII trajectory to Gromacs

[Mengjuei Hsieh]

Hi,

I was trying to use g_cluster to analyze my Amber trajectory. I renamed it
to *.g87 and g_cluster called trjconv automatically. But I found even if I
already specify it's a trajectory without box, it still asked me to enter
the box info (so far I just type in 0 0 0). Is it a kind of bug?
