I did this before, yet I want an image with voxels in a specific mask.

B=i2

A=i1+1

Then, A+B=gives me C which should contain three values

Then I tried to threshold the last image to be i1==2 However this did not work.

When I look at the images I find values of 2.00002 and 2.003 and 0.999

I should not get these values but not sure what happened.

I am sure that my masks contain 1s and 0s

Hello,

You can multiply the mask 1 with a certain value and leave mask 2 as it and then add the two to make mask three and check voxel values to understand if it is mask1/2 specific.

Hope this helps

Hi all,

I have two masks all bin. Can I use how can I use ImCalc to see voxels specific to mask one and then voxels specific two mask 2 ( in two separate images ).

So I want

Vox_only_in_mask1= ....
Vox_only_in_mask2= ....

Thanks

AS
