I have microCT image data which I have been segmenting using FEI Amira and now I need scale bars for the publication figures. Amira however does only display "1 unit" as unit and I have no idea how to get the program to read the actual scale from the image data. I didn't do the scans myself, I am only working with them, but I imagine the measurements have to be listed somewhere in the file's meta data.

So my question is, how do I get a proper scale bar in millimetres or centimeters which uses the actual measurements from my CT images?

Thanks in advance!

So I was creating a label file for my CT dataset at home with a free trial version of Amira, which is the most current version I believe (2019.1).

When I tried to show my current results to my supervisor at the university PC (which has Amira 6.4 installed), the software was not able to open the label file, even though the data set from which it was created is exactly the same!

Opening the label file in Amira 6.7 worked without any problems, however!

So my question would be if there is a known backwards compatibility issue with Amira 6.4 or is there something else I may have missed?

Is there any other solution on how I could get my label files to open in older Amira?

Thanks is advance!

I am a master student of biology and was looking for an alternative (and free) software that can do similar stuff to Fei Amira (viewing and marking structures in single microCT images and creating a 3D reconstruction of the entire stack). Are there any similar programs which can do these tasks?

I do only have access to a Pc with Amira at my university and was looking for software I can try out at my home computer too and maybe achieve similar results.

Any input appreciated!

Thanks in advance!
