Recent AFNI Changes - Aug 2005

• Some new commands available to drive AFNI from a script: SAVE_JPEG, SET_DICOM_XYZ, SET_XHAIRS. See file README.driver for the documentation.
• Program aiv (AFNI Image Viewer) can now accept image input from a TCP/IP socket, so that it can act as an "image display server" for other programs. This will be used by Daniel Glen as a tool for visualizing the results of his in-progress nonlinear anisotropic smoothing filter program.
• Updated program cat_matvec to allow input of matrices from AFNI .HEAD file attributes and also directly from the command line.
• From now on, unless environment variabl AFNI_ALLOW_MILLISECONDS is set to YES, AFNI programs will convert MSEC time unit datasets to SEC on input and output.
• New program 3dLocalstat computes a dataset whose voxel values are local statistics of a region around each input voxel (e.g., the median over a sphere of radius 9 mm).
• Some new keyboard shortcuts for the image viewer window:
  • m = toggle Min-to-Max on and off
  • a = fix aspect ratio
  • l = Left-Right mirror
  • s = sharpen image
  • D = open Disp control panel
  • M = open Mont control panel
  • S = start Save operation
• A new -FILE option to program waver lets you input your own impulse response function in the form of a .1D time series file, so you don't have to rely on the pre-programmed IRFs.
• The new @auto_tlrc script is now available to automate the +orig→+tlrc transformation. This is still experimental, and has been observed to fail on 1 brain out of a sample of about 200 (someone with extremely enlarged ventricles).
• Dimon updates:
• Dimon now has the ability to organize DICOM files, before processing, via the '-dicom_org' option.  This may be necessary if the filename order does not match the volume/time order.  Note that Dimon will not do this in real-time mode, at the scanner.
• -GERT_Reco : have Dimon output a GERT_Reco script, which in turn can be run to create AFNI datasets
• -sort_by_num_suffix : sort files according to their numerical suffix, instead of the normal alphabetical sort
• -rev_sort_dir : reverse the sorting direction on filenames
• -rev_org_dir : reverse the organizational sort by -dicom_org
• -tr : this TR overrides what is read from image files
• In 3dresample, the -dxyz option will now override the respective values from a -master dataset.
  

Bug fixes are not noted here. (Yes children, AFNI does contain bugs, unlike some software packages I will not name.)
