Greetings again,
I've attached a graph which shows the difference - the data was
generated using the following function:
y = 2 + 0.5x + Error
where x is a simple sequence between 0 and 10.
There are two regression lines through the graph. The one in blue fits
a model including the intercept term, the one in red fits a model
without an intercept. You can see that the red line takes on a value of
0 when x=0 - and that therefore the fit is not as accurate as the blue
line.
None of this stuff is specific to glim_image - this is all standard
linear model statistics. One of the best online references that I know
about is here:
http://www.itl.nist.gov/div898/handbook/
though there surely are others as well.
Good luck,
Jason

<excerpt>Hi Jason,
Well I have to say that I don't use glim_image to perform a VBM study,
but to perform a t test at each voxel to assess the difference between
my group of patients and my group of controls. So, I don't really know
whether I want to force to be 0 at x=3D0. (I don't really know what that

Do you think I'm using the wrong minc command, and if yes do you have
another idea?

Is there any reason to force the slope to be 0 at x=3D0? If you have
standard VBM density data, then that is an invalid assumption, since
there is every reason to allow the y to take on an arbitrary value at=20=
x=3D0, so you would include that column of ones for your intercept term.
If you have different data then this assumption might be valid -=20
something that is the case, for example, when looking at asymmetry VBM.
But by and large you will want an intercept.
Hope this helps,
Jason
