Dear SPM'ers,
I just have a simple question concerning plotting and
realignment.
Plotting:
I want to be able to plot the raw voxel values vs. a covariate
of interest at a particular region, however, I seem to be able
to just generate plots of the fitted and adjusted data vs. the
covariate. I'm looking to use a spreadsheet to analyze the data
and so I would need the numerical values and not just the plot
itself. I'm thinking there must be variables within the
spm_graph.m routine which I can extract these data from.?
Realignment:
We are seeing a relatively constant shift in activation areas
with our analyses (1-3mm) when compared to previous functional
brain imaging studies. I'm wondering whether the error:
Realigning Subject 1: Warning: Requested axes limit range too
small; rendering with minimum range allowed by machine
precision.
> In C:\SPM99\spm_chi2_plot.m at line 65
In C:\SPM99\spm_realign.m (realign_series) at line 221
In C:\SPM99\spm_realign.m at line 106
In C:\SPM99\spm_realign_ui.m at line 366
may have anything to do with it or whether it may be a
normalization factor (using different templates). What is this
error?
Thanks,
