Although I have successfully used clustsize for identifying clusters of atoms, I am stymied by the -mol option for evaluating clusters of molecules. A command such as:
gmx clustsize -s system1.tpr -f system1.xtc -nc -n index.ndx Works fine for obtaining information about clusters of atoms, but: gmx clustsize -s system1.tpr -f system1.xtc -nc -n index.ndx -mol gives a fatal error in Source file: src/gromacs/fileio/matio.cpp (line 681) My index file consists of the list of atoms under headings like [HP6].
