Hi,

I have downloaded the last version of brainstorm and I’m now unable to display sources when they are subtractions or averages of different source files.

Error :
line 83 : in_bst_data
Unable to read file …

Thanks for your help,

Mélanie

Bonjour Melanie,

Can you post the full error message here?
Can you send one example of files you cannot read anymore?
(upload it somewhere and send me the link in a separate email)

Thanks
Francois

Hi François,

Here is the full error message :
Error: Line 83: in_bst_data (line 83)

Here is one example of the source file I can’t display (subtraction between 2 conditions, I have the same error message for source averages):

Path: E:\Arithm\data\sources\brainstorm_db\ArithmMEG\data
Name: Subject31/Sleep_MEG_Mlt_1-Sleep_MEG_Mlt_0/results_150310_2224.mat

PS : the space in ‘dat a’ in the path does not appear in brainstorm or matlab, it should be an error when pasting

Ok, bug identified and fixed.
It came from a modification for fixing the dSPM values added late last week.
You can update Brainstorm and try again.

Thanks for reporting the problem
Francois

Perfect.

Thank you very much,
