Is it possible to perform single contrasts with dpabi Viewer when doing ANOVA with Repeated Measures?

Submitted by crmartir on

Hi dpabi team,

I have performed statistical analysis with dpabi (ANOVA Repeated Measures) and now I want to view my results. Moreover, I have revised all course video tutorials many times, but I have not find the way to perform single contrasts (like in SPM) when doing an ANOVA. I know how to display the resuts when performing t tests (for example, I have used dpabi Viewer to see the results from a pair t test) but I do not know how to select single contrasts when one has three conditions in the analysis.

Thanks in advance. Any suggestion will be very appreciated.

Sincerely,

Cristian.

Hi Cristian, I am sorry I are not sure what is "single contrasts", Do you mean you need perform One-way ANOVA with SPM? I think SPM can output a F maps after ANOVA. Or you can use DPABI's statistical toolbox to do it, then you need select F maps what you get. Hope this helpful:) Best, Sandy On Thu, Oct 09, 2014 at 09:06:34AM +0000, The R-fMRI Network wrote:

Hi,

I cannot find this function on the Statistical Analysis GUI. I have seen the file on the programm folders, concretely, on the Statistical Analysis folder. However, there is no any function to define contrasts between groups - because I have three groups. 

Thanks in advance, any suggestion would be appreciated.

All the best,

Hi,

To use that function, you have to familliar with programming, define the contrast in the command line. There is no GUI for defining contrasts in DPABI, although you can use paired t-test GUI to do paried t-test as post-hoc analysis after one-way ANOVA.

Hi,

Thanks for the valuable help. I wll try to do the post hoc analysis as paired t test.

All the best,
