Re: [Freesurfer] Fwd: strange eTIV values

Hi Douglas,

Yes, I compared the eTIV values in the SPSS and in the individual
aseg.stats files and I noticed that Freesurfer export this kind of measures
with a precision of 6 decimals (eg. 1418761.222904)

The problem is that when I send these values from the txt (that contain all
the measures of the aseg.stats file) to SPSS.

I will try to send the data from the txt to the SPSS without any distortion
in the number of decimals.


Any help will be appreciated.


Best,

Canyou give more info on how you arrived at those numbers? Eg, are those 
the numbers after you imported into SPSS? If you look in an individual's 
aseg.stats file, do you see the same value?

To: Freesurfer support list 



Hello Freesurfer experts,


When I exported the Destrieux and Desikian-Killiany volume values from
Freesurfer to SPSS I obtained "strange" eTIV values with 16 digits as
follows:

101,632,104,008.
134,253,072,953.
155,967,056,944.
142,085,122,028.
181,105,664,397.
118,051,287,519.
896,135,067,103.

With how many decimals Freesurfer exports the eTIV values ?, that is, what
is the precision of this measure? I do not know how many decimals this
measure has.

Another doubt, it is necessary to make some kind of numerical
transformation on the eTIV values before including it as a covariate in the
statistical analysis (for example, a logarithmic transformation).


Best,
