[Chimera-users] scripting & density

[Dougherty, Matthew T]

Considering the files are 64GB in size, what would be more efficient, chimera script or python?

10% difference, 10x, 100x, etc

Hi Matt,

  You would use vop threshold to make a map that has only the values 50-74 and then subtract it from the original map, and repeat with the range 90-110.

vop thresh #0 min 50 set 0 max 74 setmax 0
vop subtract #0 #1

Hi,

I have a dataset, its values are 1-255.  I would like to modify the density values using a script.
Specifically, I would like to set density values 50-74 & 90-110 to the value of zero.
Is there a way to do that using scripting, or do I need to do that using python?
