Dear GMX useres

I am trying to convert .OFF and .FRCMOD files obtained from AMBER parameter
database (Bryce Group: Computational Biophysics and Drug Design -
University of Manchester)
<http://sites.pharmacy.manchester.ac.uk/bryce/amber> to the format that
GROMACS is compatible with in .rtp files*. so referred to GROMACS tutorial
protein-ligand complex and downloaded acpype. installed it using its
readme.txt file but whenever i typed    ../acpype.py -i FFF.pdb   At folder
*acpype/test*   (/Downloads/acpype-master/acpype) or
(/Downloads/acpype-master/acpype/test) faced to this error:*

*bash: ../acpype.py: No such file or directory*

*while when I typed whereis acpype in terminal , the operating system says

*acpype: /usr/local/bin/acpype*
* it means there is the executable file of acpype . so how come I type
../acpype.py -h or ../acpype -i FFF.pdb , the system says NO such file or
*Is there anyone who ca help me?*
*I really would be appreciated it if one help me to solve this and can
convert the AMBER format files to GRMACS format files.*

*best regards*
