Dear All,

I tried to use the following command line

pdb2gmx -f -i brady.pdb -o brady.gro -p brady.top -ignh

But  I get the following error massage

File input/output error:
eiwit.pdb

So I tried to modify aminoacides.dat to include all the required aminoacids residues but , I failed because these files are readonly .
So, How can I fix this problem.

Cheers,
Asmaa
