Nisanova

Nisanova performs a voxelwise multi-factor analysis of variance of neuroimaging data.

Invocation

java  Nisanova

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

Design file
Text file with design levels and corresponding image files.
Output directory
Where the output images will be placed.
Output stem
String to use as the base for output image names.
Factor names
Names of all the factors as listed in the design file. These names should be short, since they will become part of the filenames for the output images (except for the first factor, which is the random factor). See the man page for nisanova for more details.
Threshold
No calculations are performed on pixels below this value. Choose this value such that most brain matter is above the threshold, and most non-brain matter is below it.
Verbose mode
Checking this will print out each slice number as it is processed as well as how many pixels are completed. At the end, it will print out the names of the images written out.
Check cell counts
Checking this box will produce a table of counts for each combination of factor levels in the design file so as to verify a balanced design or to diagnose an unbalanced one.
