Hi, Could I check if there is a command line version of the "center" button under Origin Index in the Volume Viewer? Thank you! [cid:image001.png@01D2F697.ECEEC010] Warmest Regards, Yong Zi Tan
Hi Yong Zi Tan, Sorry, I don’t think there is a command that automatically does the same thing as that center button. However, here is an “originIndex” option of the “volume” command to set the values directly. <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/volume.html#dimension...> Since the center button just specifies the middle of the grid, <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/volumeviewer/volum...> … you only have to know the grid size. For example, if I have a grid size 45 X 41 X 42, the center button sets the origin index to 22 20 20.5 … so I guess you would subtract 1 from each number and then divide by two to get the values to use with the “originIndex” option of the “volume” command. Just make sure to test this in a few cases, to confirm that the center button does give you the same values you calculated from the grid size. I hope this helps, Elaine ----- Elaine C.
