[GenABEL-dev] [ProbABEL] Different results when using fv and regular input on 64 bit Linux

[L.C. Karssen]

Dear all,

While preparing (yet again) to make a release of ProbABEL I ran into the
following problem: running the test suite (make check) on my 64 bit
Ubuntu 11.10 machine results in different output for the --mmscore tests
(examples/example_mms.sh), the others (I haven't tried the cox test yet
as it takes several hours) pass.

See the attached file for the complete output but as you can see in the
following few lines of diff output, the difference is sometimes a few
decimals, but in another line I simply get zeroes for beta and se_beta
in the filevector output:

< rs735579,A,B,0.5847,0.5847,0.5847,0.5847,491,0.534623,1.63067,0.488552
< rs9088604,A,B,0.5847,0.5847,0.5847,0.5847,497,0.435614,-553.621,1.12808
< rs1413801,A,B,0.5847,0.5847,0.5847,0.5847,492,0.311992,-6.1979,0.576774
< rs4911638,A,B,0.5847,0.5847,0.5847,0.5847,496,0.150202,75.6816,0.592895

Strangely enough, on my 32bit Ubuntu 11.04 laptop all tests always pass.

Can someone else please run the checks on a 64 bit Linux or other
platform? To make sure you are testing the same version, please use SVN
r.847.


Thanks a lot!
