Dear Manik, Great that you're trying to apply FieldTrip to non-neuroscientific data. As you probably know, FT is developed for the analysis of electrophysiological data, but that does not mean it cannot be useful to you. W.r.t. your data format, i think it is easiest if you read in the data into Matlab using a function like readtxt.m, and than put these data into a FT-type structure, and run your actual analyses. At the minimum, this structure should look like this: data =       label: {187x1 cell}    % channel labels (e.g. 'air pollution site 1','air pollution site 2', etc)      trial: {1x266 cell}    % data (Nchans*Nsamples) for each trial (if you have only one long data set, it means you have only 1 trial; if you have multiple 'recording sessions' from the same site, you would have more)       time: {1x266 cell}    % time axis for each trial    fsample: 300             % sampling frequency It would be great if you would be willing to share your results when they are published and add a FieldTrip reference (http://www.hindawi.com/journals/cin/2011/156869/). Good luck!
