When doing a quality control check of image data, one useful thing to look at is the histogram of the image intensities. When presented with masses of images, it’s useful to look at one histogram for each image in a big panel.
This MassHist.m script (for SPM) will print to PDF a ‘gang’ of histograms for all the images provided. The lay out has 2 columns and 5 rows on a portrait-oriented page, but these are easily changed in the code.
