Dear Aritz,

To make sure that all images have the same size in the most strict way possible, you have to provide explicitly the width and height to the 'save' command. Additionally, you can use the 'windowsize' command first to have an idea of the aspect ratio that you want in the final figure (not strictly necessary, but I find it helpful). Here is an example where I clearly define windowsize, pixelsize and output image dimensions:

windowsize 1024 1024
camera ortho
open tomos/50.mrc
zoom pixelsize 1.0
vol #1 planes z,232
volume #1 color black sdLevel -2,1 color gray sdLevel 0,1 color white sdLevel 2,1
save Tomo50_slice232.png transparentBackground true width 4096 height 4096 supersample 3

Hope this helps!

Best wishes,

Dear Sir or Madam,

I am trying to make a default .cxc file that I can use to automatically save the view for publication. I am using the following:

save /path/image.tiff pixelSize 0.05 supersample 4

This turned out to give me the best files for most cases, but depending on the zoom I get different file sizes. Is there any way to have a standard command that gives me high quality images and that always have the same dimensions regardless of the zoom? I understand that the issue comes from the different pixel size of the zoom and that I am specifying a pixel size on the command, but when trying other alternatives I have not been successful to get proper images...

All the best,

Aritz
