Sdt Load Options

 

  
Figure 9: Sdt format options popup window

For loading an image set with sdt format, the options are shown in Figure 9. See Appendix A for a discussion on the sdt format. The following is a list of steps for specifying options for the loading of an image with sdt format:

1. The first step in loading a sdt image is to specify the spatial and temporal parameters. When the popup window comes up, the (9-1) and (9-2) fields are set to the indices that yield the full spatial extent of the image volume. Thus the first plane is set to 0 and the last plane is set to the number of planes minus one. For stim files the temporal range is specified by the (9-3) and (9-4) fields, and by default are set to yield the full temporal range. A subset of the data can be specified by modifying the planar and temporal range. As anat files are only 3D spatially, the last time field is not displayed, but the first time can be used to select a particular volume out of a 4D data set.
2. When loading stim image files, the (9-5) option is available. When this option is selected, the image volume(s) specified for loading are appended across time to the currently loaded stimulation set of image volumes. Note that the new image volumes to be appended must have the same spatial dimensions as those currently loaded.
3. Lastly, when all the options are set, press the button (9-6) to invoke the loading process. See Section 7 for the procedure to display the images.
