cplex error about nirstorm

[Edouard2laire]

Thanks for the feedback. I'll try to installl the new version on my side too. In the mean time, could you let me know that does the following commands return :

cplx = Cplex();
cplex_version = nst_strsplit(cplx.getVersion(), '.')
length(cplex_version) 
str2double(cplex_version(1))

Hi,
0d63931 should fix the issue. Please update NIRSTORM and try again :)

Hello Edouard,

Thank you for the quick reply, I ran first your script and this error came back:

Undefined function or variable 'nst_strsplit'

Then I updated NIRSTORM and run the OM (same parameter as before) and this error came up.

I was finally able to get my hands on version 12.3, however it does not run on windows 10 only windows 7 and it doesn't seem to have the matlab file needed to include in matlab for the OM to run, I still need to try though. If ever its possible to make it run on newer version such as 12.8 would be great (12.8 contain the matlab file needed for matlab).

Than you Edouard

[Edouard2laire]

The code should work with the new version of CPLEX (12.8).

yes, i just saw i forgot to push some changes:

line 112-113 (https://github.com/Nirstorm/nirstorm/blob/master/bst_plugin/OM/process_nst_OM.m#L112-L113)

    i_atlas_head = strcmp({sHead.Atlas.Name},optionsAtlas_head);
    i_scout_head = strcmp({sHead.Atlas(i_atlas_head).Scouts.Label}, optionsROI_head);

should be replaced by:

    i_atlas_head = strcmp({sHead.Atlas.Name},options.Atlas_head);
    i_scout_head = strcmp({sHead.Atlas(i_atlas_head).Scouts.Label}, options.ROI_head);

I will merge it next week along with other changes. but you can already make the fix locally.

However, in your case, as you are not putting constraints on the localization of the optodes on the head, you should not select "FluenceRegion" and "FluenceExclude" as a head scout but check the "Use default search space" button.
Using FluenceRegion as a region would work too but is way too computationally expensive as you would need to compute the sensitivity to the ROI for all vertex of the head when you know that the montage should be "above" the ROI. That's why when selecting default search space, you will only look for a region 4 or 5cm away from the ROI.

Thank you Edouard, indeed it works now.

You were right also for the constrain, take way less time with the default search space.

Thanks again, really appreciate it

Alex
