    Hello,

    I tried to reproduce your subject.mat files. I understand one colonn by time-series and region. I extracted (using marsbar and my data) the Bold signal in each region and I found higher values (300, 350, etc..) that correspond to intensity values.

    I would like to know what represent exactly the values in your subject1.mat file. I found these values very low (0.0014, 0.00085, 0.0020, etc..).

    Thanks for your response.

    Hi Giovanni,

    Could you also send me one of your matrices (preferably one that corresponds to the nifti file I asked you in the previous email)?

    Best wishes,

    Joana

    Hi Joana,

    I extracted (using marsbar and my data) the Bold signal in each region and I found higher values (from 500 to 900), too.

    I would like to know what represent exactly the values in your subject1.mat file. I found these values very low and negative.

    Thanks
    Gozde
