[Optseq-commits] Segmentation fault: 11

[Vicky Lai]

Dear optseq developers,

I downloaded optseq2 and ran the following command line. I received some (error) messages that I don't understand. Can someone help? 

Here's my command line:

./optseq2 --ntp 192 --tr 1.875 --psdwin 0 13.125 --tnullmin 1.875 --polyfit 2 --ev evt1 1.875 6 --ev evt2 1.875 6 --ev evt3 1.875 6 --ev evt4 1.875 6 --ev evt5 1.875 6 --ev evt6 1.875 6 --ev evt7 1.875 6 --ev evt8 1.875 6 --evc 1 -1 0 0 0 0 0 0 --evc 0 0 1 -1 0 0 0 0 --evc 0 0 0 0 1 -1 0 0 --nkeep 6 --o vic1 --nsearch 10000

Here are the messages I received (The rank-deficiency message came out repeatedly):

/usr/pubsw/packages/vxl/1.9.0/src/core/vnl/algo/vnl_qr.txx: vnl_qr<T>::solve() : matrix is rank-deficient by 41

There are outputs though. I just don't know if I can trust the output schedules: 

Vicky$ ls
optseq2			vic1-002.par		vic1-004.par		vic1-006.par		vic1.sum vic1-001.par		vic1-003.par		vic1-005.par		vic1.log		vic1.xtxideal.mat

Vicky$ less vic1-001.par 

 0.0000    6    1.875   1.0000          evt6
 1.8750    0    1.875   1.0000          NULL

16.8750    0    1.875   1.0000          NULL 


I also tried --tsearch instead of --nsearch. I specified 8 hours with the intention of letting it run overnight. However, it says "Segmentation fault: 11". Does someone know what this means and what the solution is? Does it have to do with my computer? My work computer is Mac 10.8.5, mountain lion.

Thanks!!

Vicky
