statpar

Dear experts,

When I coregistered a result map to T1, the information in the ‘statpar’ field was lost and I need it to continue with other steps. Is there any way to perform the coregistration without losing this information?

Thank you in advance.
Best regards,
Marina

You can attach statistical parameters to a subbrick volume with 3drefit -substatpar. These are the parameters from the help:

-substatpar n type v …
Attach to sub-brick #n the statistical type and
the auxiliary parameters given by values ‘v …’,
where ‘type’ is one of the following:
Stat Types: ~2~
type Description PARAMETERS
---- ----------- ----------------------------------------
fico Cor SAMPLES FIT-PARAMETERS ORT-PARAMETERS
fitt Ttest DEGREES-of-FREEDOM
fift Ftest NUMERATOR and DENOMINATOR DEGREES-of-FREEDOM
fizt Ztest N/A
fict ChiSq DEGREES-of-FREEDOM
fibt Beta A (numerator) and B (denominator)
fibn Binom NUMBER-of-TRIALS and PROBABILITY-per-TRIAL
figt Gamma SHAPE and SCALE
fipt Poisson MEAN

But you can also copy the statistical attributes like these from one dataset to another. This only works to copy all the attributes, not just a selection.

3drefit -atrcopy func_slim+orig. BRICK_STATAUX -atrcopy func_slim+orig. BRICK_STATSYM temp_func2+orig.
