[W2mhs-commits] W2MHS error upon segmentation in Matlab

[Anup Bidesi]

Dear W2MHS group list,

I am testing W2MHS tool using SPM12 on Linux OS ( Ubuntu) to segment WMHyperintensities.

Upon running the tool withT1 and FLAIR input scans: at Matlab command prompt see below ( see run status as below:

Done segmenting subject : SVtest_op_SV_wmh using RF Regression method

Post processing and cleaning up the segmented outputs of subject : SVtest_op_SV_wmh


and then Matlab crashes see dump file attached in the 2nd one (Abnormal termination:
Floating point exception).


I have taken SPM12 updates (r6906) and spm12_mexglx updates as well.  Wonder what could be causing this error  below:

Abnormal termination:
Floating point exception

Is this is a Matlab issue or some files within SPM12 updates have to be cleared ?

Thanks & Regards,
