Displaying points using MRIcro
MriCro has a hidden feature that allows you to display points on chosen slices of a brain image. Load the brain image. Go to the Options menu, and select the slices you want to display the points on in the multislice options:
Right click on the Multislice button:
You will get the following dialog box:
Click OK, and then select the text file with the points you want to show. Note that the text file must be in DOS format, with CR/LF line endings; use the unix2dos utility to convert text files in Unix format if necessary. Here is an example text file with insula points:
--- Text file contents follows --- -35 -3 -2 1 1 255 35 -11 9 2 1 65280 -38 -3 9 2 1 65280 -38 6 4 2 1 65280 -40 6 -2 2 1 65280 -35 -3 -2 2 1 65280 -35 0 2 3 1 65280 -43 8 3 3 1 65280 35 -11 -2 4 1 16711680 38 -6 4 4 1 16711680 35 31 9 4 1 16711680 46 11 9 4 1 16711680 -32 22 15 4 1 16711680 --- previous line is last line of text file ---
This file displays selected points from an meta-analysis of insula activation. Here is the output on a standard 1mm template with the slices as shown in the options:
