How does one "optionally" use a small amount of RAM?

ON the main LAVA page, it says, "optionally using as little as 5.2 GB of RAM." How do I make it use less RAM?

The two things you can do are:
- Filter the reference dictionary using
lava filt
. Just make sure to setGEN_FLT_DATA
to1
before generating the dictionaries. - Use a compact pileup table by setting
PCOMPACT
to1
.
The constants are all defined in include/lava.h
. Let me know if you run into any issues. Also note that the RAM usage will be dependent on the size of your SNP list; that 5.2 GB number is based on the SNP list from the Affymetrix SNP array.
