Dorsal and ventral horn GM extraction script output

SCT
1

I am trying to do a dorsal and ventral horn GM volume analysis. Haven’t run into any errors, just want to make sure I’m positive about what each column of the csv output I’m getting represents.

I think the first six columns are pretty clear: timestamp, SCT version, file name, slice, VertLevel (for me, 5-7), and Label (e.g., GM left ventral horn). The remaining three columns are “Size [vox],” “BIN(),” and “STD().”

I want to double check that Size [vox] is the value generated by counting the number of voxels in the tract of interest, BIN() is the extracted GM metric using the bin method, and STD is the standard deviation of the metric. Is this correct?

Thanks!

Hi @annekbaker,

Thank you for reaching out. You are correct: “Size [vox]” is the value generated by counting the number of voxels in the tract of interest (it could be partial voxels), “BIN()” is the extracted metric using the bin method, and “STD” is the standard deviation of the metric.
