When running the script: cfg = []; cfg.template = {'D:/MEG/MEG_subj1.ds', 'D:/MEG/CriticConsc_CriticConsc_20081028_01.ds', 'D:/MEG/CriticConsc_CriticConsc_20081028_02.ds', 'D:/MEG/CriticConsc_CriticConsc_20081028_03.ds', 'D:/MEG/CriticConsc_CriticConsc_20081030_02.ds', 'D:/MEG/CriticConsc_CriticConsc_20081130_01.ds', 'D:/MEG/CriticConsc_CriticConsc_20081209_01.ds', 'D:/MEG/CriticConsc_CriticConsc_20081210_01.ds', 'D:/MEG/CriticConsc_CriticConsc_20081211_01.ds', 'D:/MEG/CriticConsc_CriticConsc_20081212_03.ds', 'D:/MEG/CriticConsc_CriticConsc_20081212_04.ds', 'D:/MEG/CriticConsc_CriticConsc_20081212_05.ds', 'D:/MEG/CriticConsc_CriticConsc_20081216_01.ds'}; cfg.hdmfile = strcat(lower(tata),'.hdm'); cfg.inwardshift = 1.0; cfg.feedback ='no'; realign = ft_megrealign(cfg, toto); I receive the error message: "the input is timelock data with 274 channels and 2222 timebins Warning: reconstructing sampleinfo by assuming that the trials are consecutive segments of a continuous recording > In utilities\private\warning_once at 75 In utilities\private\fixsampleinfo at 79 In ft_checkdata at 604 In ft_megrealign at 138 reading template sensor position from D:/MEG/MEG_subj1.ds readCTFds: In directory D:/MEG/MEG_subj1.ds, cannot find .res4 and/or .meg4 files.

hi Yoni, Is this still an issue? It is hard for us to reproduce this type of error, so could you please try again on a very recent fieldtrip version and be sure that all the matlab paths are correctly defined?

Hi, I currently cannot test it again. I will try it again in 3 weeks, as you say on a new version, though last time it I tried it was on a new version, and also all paths to the mentioned directory were defined. Thanks (In reply to comment #1)

Changing this bug's status to new (can't directly go to unconfirmed).

(In reply to comment #4) Hi Again, I think there is a bug in the 'ft_megrealign' function. When I run: **** cfg = []; cfg.template = {'D:/DATA Yoni Levy/MEG_HR/yonlev_1200hz_20100306_01.ds'}; cfg.hdmfile = strcat ('subj', num2str(ff),'.hdm'); cfg.inwardshift = 1.0; realign_file = ft_megrealign(cfg, preprocessed_file); **** I receive the output: " reading template sensor position from D:/DATA Yoni Levy/MEG_HR/yonlev_1200hz_20100306_01.ds readCTFds: In directory D:/DATA Yoni Levy/MEG_HR/yonlev_1200hz_20100306_01.ds, cannot find .res4 and/or .meg4 files. Reference to non-existent field 'res4'. " and when double checking, there are clearly *.meg4 and *.res4 files in the above-mentioned directory. Please assistance

(In reply to comment #5) ok, I found the problem: I should have defined cfg.template = {'yonlev_1200hz_20100306_01.ds'}; instead of cfg.template = {'D:/DATA Yoni Levy/MEG_HR/yonlev_1200hz_20100306_01.ds'}; thanks
