Dear all,<br>
<br>
I faced a problem in the pdb2gmx step as i got this following error message,<br>
"Fatal error:<br>
Chain identifier 'A' was used in two non-sequential blocks (residue 908, atom 7013)"<br>
<br>
As I'm pretty new to this field. I'm finding it difficult to troubleshoot. Any suggestions would be of great help.<br>
Thank you,<br>
Annie Albin.<br>
