Dear All.  I have been trying to run the PCA plugin without success.  I have got to the point where it seems to be running but I get the following error messages:

java.lang.OutOfMemoryError: Java heap space

        at bijnum.BIJutil.matrixFromImageStack(BIJutil.java:115)

The stack I am working on comprises Landsat data, each slice being about 170 Mb in size - perhaps the files are too large?

any pointers would be most welcome!
