This is 3 classes, so most of this will be covered in a blur. (note that we are not introducing Unix (afni00_unix)) afni01_intro: (skipping physics and most of afni) - 1-5 fast - 17-21 fast (21: note quadratic baseline) - 27-33 slow, fast - 36-42 slow, fast - 48-51 design - 53,54 realtime demos (no to3d): - run Dimon command from AFNI_data3/demo.realtime.run1 Dimon -infile_prefix EPI_run1/8HRBRAIN -GERT_Reco -quit - run demo.B.* : advanced realtime results #--- skip this ---# cd bad.dicom ls # order of files is not proper slice order # so "to3d -time:tz 5 34 2.5 alt+z *.dcm" # does not work properly # will need to terminate this with ctrl-c Dimon -infile_prefix image -GERT_Reco -quit Dimon -infile_prefix image -GERT_Reco -quit -dicom_org tcsh GERT_Reco_dicom afni afni04_interactive (from AFNIintergoals.txt): Tasks: A. locate data, peruse main afni GUI 1. go to AFNI_data3/afni and verify there are datasets --> cd ~/AFNI_data3/afni ; ls ; afni & 2. quickly peruse the main window - coords, Ulay Image/Graph buttons, BHelp, -> panel toggle buttons B. examine anat+orig as underlay 1. set anat+orig as Underlay, open windows, open/close graph 2. note xhairs, cardinal views, contrast/brightness controls 3. compare against Min-to-Max display (in Disp window) 4. zoom, pan, crop 5. other menus: right-click in image and in color bar C. review alignment between anat+orig and epi_r1_orig 1. set epi_r1+orig as Overlay 2. look at edges, CSF (jump-to-xyz: -2 10 2) 3. turn off/on overlay (toggle button and get 'o' from F1 help) 4. threshold overlay D. review time series, look for motion or other problems 1. set epi_r1+orig as Underlay, turn off overlay 2. note graph information, graph size and relation to Image window - note Opt->Scale/Matrix and keyboard shortcuts 3. jump-to-ijk: 22 43 12 (via right-click in image) 4. ignore 3 TRs (FIM -> Ignore) 5. evaluate motion : 'v'ideo mode (space to stop), arrows 6. pick ideal: (FIM -> Pick Ideal -> epi_r1_ideal.1D) E. overlay statistics: evaluate full-F and maybe fpos stimulus 1. set func_slim+orig as overlay, Full_Fstat as both OLay, Thr 2. set threshold to 7.0, evaluate colored/uncolored voxels - note Thr range and individual voxel values 3. evaluate colors of voxels, Inten range, OLay range, scalar, Pos button - note color at individual voxels - alter one panel range and color 4. set thresh -> 12.0, simple Clusterize, look at report (Rtp) 5. (optional) 4x3x2 coronal montage around peak F, save .jpg image 6. change OLay, Thr sub-bricks to 1,2 (fpos Coef and Tstat) - set p=0.001, note q - set color range to 2, 7 Positive colors - change one color panel range and color 7. (optional) 3 hidden menus, consider other color bars ------------- optional, continued ------------------------------------ F. (optional) histogram plugin: 1. anat+orig, note background, CSF, gray and white peaks - plot, range 300-2000, 100 bins G. (optional) dataset information: how was func_slim created? 1. Define Databmode -> Misc -> OLay info 2. note orientation, extents, HISTORY and sub-brick contents H. (optional) standard space: 1. where is the peak F-stat? - Underlay -> anat, and switch to "Talairach View" - Image window -> right click -> Where Am I? 2. Atlas Colors: hippocampus -> blue, amygdala -> red
