[BioC] MBEI on 60 U133 Plus 2.0 arrays

[James MacDonald]

Hi Kamila,

Currently you are limited by the amount of RAM you have. Technically you _could_ write a just.li.wong() that bypasses the explicit creation of an AffyBatch (as do justRMA() and justGCRMA()), and quite possibly you would be able to get away with just 2Gb RAM.

Best,

Jim
