The recommended address for asking questions about Chimera is chimera-users(a)cgl.ucsf.edu <mailto:chimera-users@cgl.ucsf.edu> ... you do not need to send another message, I have CC'd that address on this message so that somebody else can answer. I don't know the details of Windows download. My only guess is to wait for a few minutes to be sure the download is finished before you try to open it. Maybe there is a temporary filename for the partial download that changes after the download is complete. Regards, Elaine ----- Elaine C.

Problem downloading PDBs in Chimera
by Clarke, Oliver 10 Mar '25

Hi, Since this weekend, I have been unable to download PDBs from within Chimera (using "open" or Fetch by ID). The same PDBs load fine in ChimeraX or when downloaded manually. Cached PDBs load fine. Cheers Oli

Setting partial charges to a protein gives same charges in both Gasteiger and AM1-BCC methods. Is that corrects?
by teralexei＠proton.me 03 Mar '25

Dear colleagues, calculation of partial charges in Chimera looks to work improperly in my hands. After addcharge or dokprep procedures, independent on method used (am1-bcc or Gasteiger), mol2 files are just the same: @<TRIPOS>MOLECULE .... PROTEIN AMBER ff14SB @<TRIPOS>ATOM 1 N -76.5030 6.5380 -16.5070 N.4 1 ARG 0.1305 2 CA -75.2450 7.2900 -16.2110 C.3 1 ARG -0.0223 .... The problem persist in both Chimera 1.17.3 and ChimeraX. The latter gives even "NO_CHARGES" comment in both (am1-bcc and Gasteiger) cases: @<TRIPOS>MOLECULE .... PROTEIN NO_CHARGES @<TRIPOS>ATOM 1 N -76.5030 6.5380 -16.5070 N.4 1 ARG 0.1305 2 CA -75.2450 7.2900 -16.2110 C.3 1 ARG -0.0223 .... I am not an expert in molecular modeling, sorry. But I think that I am doing something wrong. Could you please help me with setting charges properly? Thank you in advance! PS. I am a newbie here. Please don't hurt me too much. Yours sincerely, Al.
