hello, i've just begun exploring EP toolkit, to work with a bunch of .set files that were created from neuroscan .cnt files, imported and epoched by event type in EEGLab. in trying to begin the "Preprocess", i'm just getting errors, using .set as an input type, 1:750 and 1:150 as points and baseline (3 second epochs) and selecting an individual subject .set file (epochs of one trial type): ??? Attempt to reference field of non-structure array. Error in ==> ep_stripAdds at 59 if ~isempty(find(strcmp('RAW',EPdata.subTypes), 1)) Error in ==> ep_artifactCorrection at 543 [data]=ep_stripAdds(data); Error in ==> ep at 727 ep_artifactCorrection(inArg); ??? Error while evaluating uicontrol Callback abandoning the Preprocess, i instead tried to create an (unartifacted) "Average" from similar .set files, but after the prompt for the save- as file type, i get: ??? Error using ==> read_header at 747 unsupported header format Error in ==> read_data at 282 hdr = read_header(filename, 'headerformat', headerformat); Error in ==> ep_readData at 554 [theData]=read_data(fileName,'dataformat',fileFormat, 'headerformat',fileFormat); Error in ==> ep_averageData at 118 inputData=ep_readData(thisReadArg); Error in ==> ep at 911 averagedData = ep_averageData (sessionFiles ,importFormat ,fileType,averagingMethod,EPmain.preferences.average.trimLevel); ??? Error while evaluating uicontrol Callback this is on Mac OS X 10.5.x, Matlab R2009a, with 4gb of RAM, and dual 2.8 Core2Duos... what am I doing wrong? or is something else going on that needs to be addressed? thanks, andrew |

How odd... I'll need you to send me a copy of your file. Could be something funky about the conversion from .cnt to .set. Use yousendit.com to send it to jd...@ma.... Cheers!

hi Joseph, sure - i tried with .set files that were saved by EEGLab both as one file and as a separate .dat and .set. both had the headerformat error, and i've put a (41mb) archive of files you can reproduce with, here: http://zaidellab.org/stage/data/Andrew/setfiles.zip thanks, andrew On Aug 27, 2009, at 5:31 AM, Joseph Dien wrote: > How odd... > > I'll need you to send me a copy of your file.

I couldn't reproduce your error. For the two file set you sent me, the names of the .dat file and of the .set file are different so they appear to be from two different data files. They need to be from the same data file (i.e., have the same name). For the one file version, it worked fine. I just made some fixes to the file I/O code though, which may account for it working okay. I'll be posting a new version of the EP Toolkit later tomorrow. I also just made a fix to FieldTrip's .set file I/O code and posted it to FieldTrip. Download the new FieldTrip build tomorrow as well (since the EP Toolkit uses FieldTrip's file I/O functions to import .set files). If you're still experiencing the error I'll dig into it further. Note that there are also some bugs in the file I/O code of EEGlab as well. If the files were originally imported into EEGlab from another source and then subsequently saved as .set files, they may be defective, accounting for the errors. I just submitted a series of bug fixes to Arno so hopefully they will be included in the next EEGlab build. I'm attaching a copy of the fixed EEGlab file in case you want to use it. Cheers! Joe |
