You cannot use NIML .dset files as SUMA .spec files. 

If the anatomical surface file (with node coordinates and face indices) is stored in a file my_surface.asc (some other extensions are supported, including GIFTI), you can view that surface in SUMA using:

	suma -i my_surface.asc

and then, in the SUMA viewer object-controller window (ctrl+s), click ‘load set’ to select a NIML .dset file.

A .spec file defines file names and other properties for a set of anatomical surfaces that can be shown in SUMA. An example of how a .spec file is organised is  lh_ico16_al.spec included in the tutorial_data_surf*.gz [1].
