Re: [Freesurfer] Fwd: Comparing HRF undershoots between conditions
Hi Doug, Sorry to follow this topic with a delay but we tried to model BOLD signal undershoot with a gamma function and we failed. The problem is, gamma function generates positive values and we can NOT use inverse gamma function (or otherfunction similar to that) as a part of mkanalysis-sess (for modeling BOLD signal undershoot). We even used matlab gammafit to estimate parameters and it said that values should be positive otherwise gammafit function fails. Do you have any suggestion?

Re: [Freesurfer] Fwd: Comparing HRF undershoots between conditions
What do you mean the gamma function generates positive values? It will create a regressor with a positive-going HRF. However, the regression coefficient can be negative which would invert the shape. The reg coef is fit to the data, so the data will tell you whether there is an undershoot or not. doug On 04/24/2013 03:02 PM, SHAHIN NASR wrote: Hi Doug, Sorry to follow this topic with a delay but we tried to model BOLD signal undershoot with a gamma function and we failed.

Re: [Freesurfer] Fwd: Comparing HRF undershoots between conditions
You don't generate a negative coefficient. The sign and magnitude of the coefficient is determined by the fitting procedure. It may be the case that a positive coef fits the data better than a negative. You should not change the gamma parameters. doug On 04/24/2013 04:06 PM, SHAHIN NASR wrote: I know but how can we generate negative coefficient? To clarify, we use alpha=2, delta=2.25 tau=1.25 to generate default HRF. Using negative values for alpha, delta or tau, does not invert the shape of the curve (HRF).

Re: [Freesurfer] Fwd: Comparing HRF undershoots between conditions
Sorry that I keep on asking questions but I want to know if using a model can significantly increase the chance of getting a significant response. As far as I see for the positive peak, when I use a model (e.g. gamma model or spmhrf), I see a more significant response compared to when I use the FIR model. Is it correct? If true, then the same might be correct for the negative peak. P.S.: To be more clear, I am talking about the response maps relative to the baseline.
