Hello,
I have tried almost every possible option of the GUI to see if there is
something i am messing up but nothing really seems to help. I am trying to
run Feat for one of our event related study with several EV's. When i run
the same experiment with the same set up in SPM, SPM does show me
activations however FSL doesnt !!! I am really confused and any help will be
greatly appreciated. I have posted my issues earlier and yet for some reason
or the other i just dont get to see the activations.
there are a total of 14 EV's in the design
TR=1.5 sec,
FWHM=9mm,
486 volumes, 6 volumes to be deleted,
High pass filter = 30,
I am using the option of full model set up and my EV's follow a 3 column
format,
convolution : Gaussian
I am trying to look at the uncorrected voxel p threshold 0.05; Z threshold =
1.64
My data is 4d
Original onset files were in terms of volumes so in order to get them
converted into time in seconds i have multiplied each of the values in those
files with TR.
e.g one of the onset files in a three column format
78.1965 2 1
91.2405 2 1
104.284 2 1
130.338 2 1
143.365 2 1
182.46 2 1
208.53 2 1
404.025 2 1
547.365 2 1
612.525 2 1
703.74 2 1
I already ran MELODIC on 15 subjects and also on just one subject to check
the number of independent components and everytime i end up getting some 200
to 240 components. I am not even sure if this is a realistic number for the
components. Could it be that my data is messed up ?
Thank you in advance
sincerely,
Ankit Master
