Hello Jeni,

>>
>> Warning: spm_XYZreg: Co-ords rounded to

>> In spm_XYZreg at 490
>> In spm_results_ui>mychgcon at 1227
The warning is actually pretty informative: you selected a point to view
your results, and but no information was available at exactly this
point. In your case, the discrepancy is 1.16 mm, which is not too bad.
There are cases in the archives where this was much bigger (>10cm) and
indicated a problem with the data, but in your case, I would not be
overly worried as the distance is small.
Cheers,
Marko
