Dear Justin, I replied the thread already, but it is waiting for approval due to large email content. Could you please approve it?
I have no control over that. If it's too much for an email (normally pdb2gmx output is fine) then upload to e.g. pastebin and provide the URL.

Perhaps your atom and/or residue naming needs to be fixed. However, the residue 1 in the PDB is: ATOM 1 N ASP L 1 24.330 14.711 -3.854 1.00 0.00 N ATOM 2 CA ASP L 1 25.669 15.093 -3.310 1.00 0.00 C ATOM 3 C ASP L 1 25.766 14.899 -1.791 1.00 0.00 C ATOM 4 O ASP L 1 26.581 14.101 -1.318 1.00 0.00 O ATOM 5 CB ASP L 1 25.989 16.552 -3.646 1.00 0.00 C ATOM 6 CG ASP L 1 26.260 16.773 -5.128 1.00 0.00 C ATOM 7 OD1 ASP L 1 26.489 15.809 -5.821 1.00 0.00 O ATOM 8 OD2 ASP L 1 26.236 17.903 -5.554 1.00 0.00 O ATOM 9 1H ASP L 1 24.318 14.855 -4.844 1.00 0.00 H ATOM 10 2H ASP L 1 24.152 13.747 -3.656 1.00 0.00 H ATOM 11 3H ASP L 1 23.623 15.275 -3.427 1.00 0.00 H ATOM 12 HA ASP L 1 26.425 14.456 -3.771 1.00 0.00 H ATOM 13 1HB ASP L 1 25.154 17.186 -3.346 1.00 0.00 H ATOM 14 2HB ASP L 1 26.864 16.873 -3.080 1.00 0.00 H You can see that the first atom is just atom N, not missing. Can I ask why I still got this error? Another mutant file of the protein works totally fine for pdb2gmx. Its 1st residue ASP is the below, I could not see any big difference except slight difference in the coordinates.
