[gmx-users] testing gromacs runs

[Ayesha Fatima]

Dear all,
I have just installed gromacs 4.6.5 in Cygwin build on Windows 7
platform. I want to test the installation but it keeps giving the
error

./gmxtest.pl all
ERROR: Can not find executable gmx pdb2gmx in your path.
Please source GMXRC and try again.

My Gromacs is installed in the C: drive outside the root. I have also
put the regression folder downloaded from
http://gerrit.gromacs.org/download/regressiontests-4.6.5.tar.gz

I sourced gromacs from inside the folder where the file gmxtest.pl is.

However when i want execute pdb2gmx, the file executes

Could you guide please?
thank you
Ayesha
