Where do AFNI Datasets Come From?
¥Method 1: Create datasets with program to3d [principal subject of this talk]
HInput files are arrays of numbers --- i.e., image files
¥Method 2: Realtime input from an external image source program
(e.g., directly from scannerÕs
reconstructed images)
HAFNI program Imon
reads image files from GE realtime EPI output, checks them for various
errors, sends them into AFNI for display and formatting --- while acquisition
continues
HSample program rtfeedme
can be used to write your own image source program
¥Method 3: AFNI programs can read other formats for display and
analysis
HANALYZETM 7.5 format Þ.hdr/.img file pairs
åUsed
by SPM and many other programs
åMajor
drawback: lack of spatial orientation and position information in header
íCan be difficult to overlay ANALYZE datasets with other
datasets
HMINC format Þ .mnc files
åUsed
by software from Montreal Neurological Institute --- mnitools
HCTF format Þ .svl files
åGenerated
from CTF MEG data analysis software package
