Are you sure you've patched your protein correctly? I don't think that your seq2psf command protects the N-terminus (hence errors about HT1-3). You may have N-acetyl coordinates with a free N-terminal parameter set.

Are they supposed to belong to the N-terminal capping? I ran a calculation and the protons do not seem to disturb but they are spreaded over a wide space. I can delete them from the template. Why are they created and how do i get rid of them in the psf file.
