Supersampling with reslice

High resolution zoomed-in images can be created either inCSPM with automatic over-sampling (or super-sampling) or manually.

• For the CSPM option, go to local settings. 
• For the manual option, from the CSPM Image menu choose Reslice

• Enter the x/y/z voxel size (e.g., 0.3 0.3 0.3)
• Enter the bounding box, which is xmin ymin zmin; xmax ymax zmax (e.g., -50 -80 -60; 50 20 0)
• Linear interpolation usually works well

If you get blank spots, it may be because you have NaN's in the image; this only happens with an image of real/floating type (as opposed to integer). You can check in mricron (see below).

To change the type (overwrites image!)

• Select from the CSPM Image menu "Change type"
• Select int16 (or int32 if you have a range of very precise values - unusual)
