FDA analysis

[dineshchemistry]

I've used FDA code (v2021.7-fda2.11) to perform analysis on my polysaccharide system (SMD simulation).
I've obtained .pfa and .pfr files.
The scripts pfa_draw and pfa_loaduser are meant for both atom-based and residue-based analysis, right?
because pfa_loaduser.tcl is throwing an error on the .pfa file
whereas pfa_draw.tcl is not working on .pfr file.
The .pfa and .pfr files are attached.
output_pfa.txt
output_pfr.txt

Your help is highly appreciated in this regard.

It seems that you are using an old version of the gromacs-fda-vmd scripts. Please find the latest version at https://github.com/HITS-MBM/gromacs-fda-vmd. The documentation and a small test case alagly are also available to check the usage.
