Appion

Artifacts were present with a prime factor of 37, but not a prime factor of 29, so setting the limit to 30.

Need to think about how changing image size will affect make stack.

Right now we are cutting center of the image out, but 3710x3838 trims to 3696x3828. Losing 14 pixels means 7 pixels from the edges, so possible each particle would be off center by 7 pixels. I would trim from the corner, but I cannot remember which corner (upper right, lower left) that I need to trim from.
