converts NIFTI_datatype=4 (INT16) to float
Hi all,
running seed Fox_tn_LP_3mm
------------------------
Extracting timeseries for seed Fox_tn_LP_3mm
Computing Correlation for seed Fox_tn_LP_3mm
++ 3dfim+: AFNI version=AFNI_2011_12_21_1014 (May 23 2014) [64-bit]

** AFNI converts NIFTI_datatype=4 (INT16) in file /home/peter/phxian/schpatient_c/sub111/func/RSFC/Fox_tn_LP_3mm_corr.nii.gz to FLOAT32
Warnings of this type will be muted for this session.
Set AFNI_NIFTI_TYPE_WARN to YES to see them all, NO to see none.

++ Output dataset /home/peter/phxian/schpatient_c/sub111/func/RSFC/Fox_tn_LP_3mm_Z.nii.gz
Registering Z-transformed map to standard space

what do you think about the warning?
how to deal with it?


Thank you..

Hello,

you can ignore that warning. Float32 allows greater numerical precision when storing the data (so this conversion is a good thing)

RE: converts NIFTI_datatype=4 (INT16) to float
Thanks Maarten.
I have another question is that,
there's no slice time correction in the scripts,
is that right?
how to add this process in the bash_process.sh?

thanks.

RE: converts NIFTI_datatype=4 (INT16) to float
thanks Maarten,
I have viewed the previous discussion in this forum,
and got lots of information about slice timing correction now.
I still have one question is that, could I get the acquisition order from the raw data (e.g., dicom),

Have a good day..

Peter
