I have already run 10ns of simulation on gromacs 4.5.3 and i have to do do_dssp on 4.5.5 of gromacs analysis, for that i have to convert my tpr file to tpx format. plz any one send me command for the conversion of tpr to tpx.
There is no such file format at "tpx" - error messages that mention "tpx" are a generic reference to the (old and unused) variants of the .tpr file. Version 4.5.5 should read version 4.5.3 files.
