Re: software/algorithm to cluster protein conformations

Hi Basak,

You can probably use the gromacs tools:
http://manual.gromacs.org/current/online/g_cluster.html

There are other tools like MSMbuilder that has clustering functionality (built partially on gromacs tools):
https://simtk.org/home/msmbuilder

For both of the above, you will need to convert the dcd file to either trr or xtc format. The former is possible using catdcd.

You could also use something like kmeans in matlab in combination with the matdcd tools. There are probably many other options that others can suggest.

Good luck.

Josh
