Description

The affinity propagating clustering program requires that all particles in a stack be inserted into memory for the cross-correlation matrix calculation.

This needs to use my new processStack class in source:trunk/appion/appionlib/apImagicFile.py to systematically read particle subsets from the a stack.

Note: program did not do a good job of comparing old version to new version.

Looks ok. Not a fan of using simf as a shorthand for similarfile but OK.
Can you assign to someone to test?

You'll need to run on amibox after Friday, May 20. Try it on a large stack > 16GB.

Dmitry, do you happen to use affinity propagation on >16GB stacks ever?

that's quite big. I don't have anything that size. I can look around other projects though

This one is too difficult to test bc we don't have any large stacks that will work. Since Neil logged it I'm assuming it worked for the data that he was having trouble with.

I think Joel reported this issue to me for data at NIS. In the past it would probably fail on stacks > 2GB. The algorithm has changed so all stacks are treated equally, so if it works on a 200kB stack it should also work on a 200GB stack.
