Hello,

I have a nifti file (myfile.nii.gz) with values between 1.2326e-32 and 5.58214e-07.
I am interested in certain percentile values, but when I use for example 3dBrickStat -perclist 1 100 -perc_quiet myfile.nii.gz, it returns a value with only the first 6 decimals, which in this case would be all zeros (0.000000) while instead I would like to get 5.58214e-07. In this specific example since it's the 100 percentile I guess I could use 3dBrickStat -max myfile.nii.gz and it will return 5.58214e-07, but I need also other percentile values and therefore I need to use the percentile options.

Is there any way to increase the number of decimals printed out or to obtain the whole decimal number with the option -perclist?

Thank you,
Giuseppe
