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
