Re: is it too BIG?

Dear Agus,
I run a model including animal, permanent environmental and QTL as
random effects for ewe trait (lsw). Variance stucture for QTL is
obtained from LOKI program.
I run the program with -S8 option and it is succesfull for up to 2000
animals in the pedigree. If I increased the number of animals in the
pedigree, say up to 2500, then the program introduced an error message
"Fault 6 Too BIG! USe -s option". ( I use ASREML [19 Apr 2000] for my
analysis).

You need a 64bit version of ASReml to access more than 2Gbyte of work
space.
The problem is not the number of animals per se but rather the fact that
the IBD matrix is dense
so the solution requires a large amounbt of space.

I am hopeful ASReml 2 will be available from VSN website from early March.
It will be available in Windows, Linux and Solaris, 32 and 64 bit
versions.
