AFNI and SUMA new features - May 2005
Submitted by rwcox. on 2005-05-02 14:11.
- In the Scatterplot plugin, added overlay of the least squares fit line (in red) between the two sets of data being graphed.
- The sub-brick choosers on the Define Overlay control panel will now resize themselves to fit longer sub-brick labels (as some people seem to generate via 3dDeconvolve). The old environment variable AFNI_BUCKET_LABELSIZE is now obsolete.
- When writing NIfTI-1.1 '.nii' datasets, AFNI programs now include more AFNI header features in the .nii file, so that re-using such a file in another AFNI program is more likely to do what you expect.
- When using waver -tstim, each stimulus time can now have a separate amplitude factor attached. Try, for example, this command:
waver -dt 1.0 -GAM -peak 1.0 -tstim 3.2 17.9x2.0 23.1x-0.5 | 1dplot -stdinEach time with an "x" after it is taken to have a scaling factor. For one possible use, see this page.
- Modified 1dplot so that if the input (from a file or from stdin) is one long line of numbers, it will plot correctly. Before, you would have to transpose such a long line into a multi-line single-column file for graphing. This change makes it easier to use 1dplot -stdin with some programs such as nifti_tool.
- The image window Button-3 popup menu now has an item to let you open the ROI drawing plugin directly.
- 3dcalc now lets you specify that the (x,y,z) coordinates
are in DICOM or SPM order.
- The default remains that (x,y,z) correspond to the order that the dataset is stored on disk; you can see this order using the 3dinfo command.
- If the new option -dicom or -RAI is given, then the coordinates to appear in DICOM standard (RAI) order, so that
-x=Right -y=Anterior -z=Inferior +x=Left +y=Posterior +z=Superior
- If the new option -SPM or -LPI is given, then the coordinates to appear in SPM (LPI) order, so that
-x=Left -y=Posterior -z=Inferior +x=Right +y=Anterior +z=Superior
- The AFNI graph window now draws little circles around graph points that correspond to time points are being 'ignored' by the grapher. The 'Ignore' level is set on the FIM->Ignore sub-menu, and is used to have the grapher not plot the first few time points of a dataset -- this is useful when graphing EPI time series, which might have the first few points be extra-bright.
