<div>Dear Gromacs users,</div>
<div> </div>
<div>I tried the grompp and I got the following message: '' Error: number of coordinates in coordinate file XXXX.pdb does not match topology (topol.top)''. </div>
<div>Is there any explanation why is this happening? </div>
<div> </div>
<div>I would appreciate any help. I am new in using MD and Gromacs in particular.</div>
<div> </div>
<div>Thank you in advance,</div>
<div> </div>
<div>Best regards,</div>
