Hi,
You need to specify the input file with -f flag and -i is for the itp file which is the output and that is any way created by default. Just remove -i from the command and it will work.
best,

Subject: [gmx-users] pdb2gmx
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
