You can preserve the existing custom groups when writing a new index file by supplying the old index file as input to make_ndx. If you're using default file names (hint: always provide your exact command!) then it will otherwise be overwritten. make_ndx -f conf.gro -n old_index.ndx -o new_index.ndx will preserve your custom groups and allow you to add new ones. -Justin -- ================================================== Justin A.
