Problem in "raw" EEG signal analysis

[Anonymous]

Dear Brainstorm expert,
I am glad to see the new version of brainstorm program. However, when I use the raw (txt) file eeg and try to analysis the data, I have some problem.
1. in importing eeg data from data manager, when I import the eeg data and finally click the import button. it always failure. I can not see the message windows tell me successfully import data.
2. when I do the analysis by RAP-MUSIC method and set the parameter RAP-music window properly, I try to click the execute the algorithm. but the matlab window shows: undefine variable "User". I can not see the result
thanks for help

Dear JLHsu,

Thanks and congratulations ! You're our first BrainStorm reporter on the forum !

1. in importing eeg data from data manager, when I import the eeg data and finally click the import button. it always failure. I can not see the message windows tell me successfully import data.

Are these data from the Sample Raw MEG data of BrainStorm or is it EEG raw data files you have created locally ?

2. when I do the analysis by RAP-MUSIC method and set the parameter RAP-music window properly, I try to click the execute the algorithm. but the matlab window shows: undefine variable "User". I can not see the result
thanks for help

Dear Dr. Sylvain and Brainstorm expert,
thanks for replay.
for the question 1. it is my lab eeg data and I convert it to .txt format. I also use the save_raw.m file to conver it as .raw format but still in vain.
thanks for help

Dear JLHsu,

Werner Lutzenberger suggest the following fixes to 'rap_music_parameters.m' while waiting for an update from us.

I made two correction to 'rap_music_parameters.m':

line 400: GUI.Results = fullfile(Users.STUDIES,newname);
> GUI.Results = newname;

line 447: Users > User

Then I all seemed to work
