Dear Charmm users,
I'm now trying to prepare my membrane proteins using charmm-gui membrane builder. I tried to upload my own PDB file but it doesn't work. I get an error saying "Submit valid PDB ID or upload custom PDB file". I don't know what wrong with it. I used the same PDB file before and everything was fine, no problems at all. But now I just want to change the lipid type so I tried to upload the same pdb file as before but it doesn't work.
I also tried the other modules in charmm-gui to upload the pdb file but it also doesn't work, got the same error.
Are there some problems with charmm-gui server at the moment or are there any way to solve this problems?
Thank you so much in advance for any helps and suggestions.
