[chimerax-users] 答复: Loading density files

[Tianming Qu]

Hi Dr. Meng,

Yes, this helps.

I can open multiple files now, but I cannot open them in the order I want. I rename them with only numbers which corresponds to the frame number of each map, how can I read them in such numbered order? Should I rename all the file exactly as in the vseries says: _stachxxxx_.dx? In which xxxx represents index of frames?

Best,
Tianming

Hi Tianming,
If the maps are on the same grids as each other, i.e. their outline boxes would be the same and they have the same number of grid points with same spacing, they can be opened as a "volume series" -- then you can play the series with the "vseries play" command or interactively using a slider interface shown with "vseries slider":

Volume series and how to open the files so that they are interpreted as series:

You might need to name the files a certain way so that you can specify them in a single "open" command.  See "open" command "vseries" option:

For playback after opening, see the "vseries" commands, including "vseries play" and "vseries slider":

I hope this helps,
Elaine
