Hi Tianming, I meant to just create the BILD file(s) directly. It is a very simple plain-text format described in the help page, which also links to example BILD files that include arrows. Details of how to do it (or script it) would depend on the format that you have now, which we don't know anything about. In ChimeraX, you just open the bild file to show the objects. <https://rbvi.ucsf.edu/chimerax/docs/user/formats/bild.html> Elaine ----- Elaine C.

Thanks a lot Dr. Meng. FYI, Is there any example script I can use as an example for using BILD to write PCA arrows?
Best, Tianming

Hi Tianming, There is no built-in option to read ICA vectors calculated by some other program. You may be able to script it yourself, e.g. by creating 3D arrows in BILD format or something like that. BILD format is a simple text input file described here:

Hi Dr. Meng,
I have the independent components calculated already, sorry I did not make myself clear. I am wandering if I can use ChimeraX to display the ICA results I got from my own calculation.

Hi Tianming, I do not know which calculation you are talking about. As far as I know, ChimeraX does not have any option to calculate independent components from an MD trajectory.

Dear all,
Is there any way I can display the eigenvectors I got from the independent component analysis on ChimeraX, which is calculated from the protein MD trajectory.
Best, Tianming
