ANCOVA - how to measure adjusted means

Hi,

I'm using Matlab2014b to run an ANCOVA on a dataset. I'm looking at how horses' stride parameters change with speed. I have an independant variable(horse speed), dependant variable (stride length), and a covariable that categorizes the foot under study as a front or back.

The group*X value interaction is non-significant, so I interpret that the two regression slopes are not sig different, but when I force the lines to be parallel, the p-value for 'Group' is significant. I interpret this as meaning that the line intercepts are different.

I'd like to measure the adjusted means for these two categorical groups (this seems to be an output from other stat packages), but can't see if Matlab provides this output. One guess is the prediction output, after exporting the model from the ANCOVA gui.

Does anyone know anything further?

Many thanks,

Chris
