Nisroi

Compute regions of interest (ROIs) from the images produced by Nisanova.

Invocation

java  Nisroi

This starts up the java interpreter and runs the Nisroi application. You need to have set up your environment for java in order for this to work.

Fmap image
Input image (produced by Nisanova).
Output directory
Directory in which the output image will be placed. This program will try to create this directory if it does not exist.
Niscrit significance threshold
Image threshold to use in finding ROIs. This threshold comes from the output of Niscrit.
Contiguity threshold
Also known as the ROI pixel size threshold, this is the minimum number of contiguous pixels needed to produce a region of interest.
3-D ROI analysis
Click this button if you would like the ROI analysis to be performed in three dimensions.
2-D ROI analysis
Perform the ROI analysis in two dimensions.
Find positive ROIs only
Checking this box will allow only positive ROIs, otherwise both positive and negative ROIs will be found.
Verbose mode
Checking this box will print a table of results on the Output window. Either way, the table of results will be written to the output .txt file.
