Hi Shabir,

There have been some changes to the PDB-reading code since the pre-1.3 version you are using. Could you get the ChimeraX daily build and try reading your file with that? Let me know what happens.

Hi Eric,

Thanks very much for your quick reply.

Ah I see I haven't updated ChimeraX for a while.

I have just downloaded the latest version and will upgrade it tomorrow.

Thanks very much.

cheers

Shabir
