I am running qdec on a Mac Pro OS X 10.5.5 with dual quad pentiums mirrored
RAID and 16GB memory.
I have followed the instruction for creating the qdec table, loaded the data
in successfully and requested an analysis with two continuous variance. The
following is the final output before it crashes because it cannot allocate
memory. I have the maximum memory in my machine. What can I do?
