The script that deals with converting trajectories is trjconv. Have a look at the documentation, that will show you the formats it can handle, no idea what Amber format is, but as long as you can get it into one of the ones it can use should be fine. Plus, with g_cluster I suspect you will require a topology file to be able to do the analysis, which will be your major sticking point.
Note that pdb2gmx converts pdb coordinate files to generate a topology file (and the residues/molecules have to be known by the database otherwise you have to make by hand etc).
