9. Command Line Control
map3d -f daltorso.fac

10. More Command Line
map3d -f daltorso.fac -p p2_3200_77_torso.data

11. Still More…. map3d -nw \ -f daltorso.fac -p p2_3200_77_torso.data \
-f dalepi.fac -p p2_3200_77_epi.data

12. All the options Map3D Version 5.3 USAGE: map3d [FILENAME]
map3d [OPTIONS]
FILENAME:
the name of a file containing geometry and/or data.
OPTIONS:
global:
-v (echo the version number)
-c colour (default colour for all meshes)
-df filename (for default settings file)
-if filename (to set output image basefilename)
-iv (initialize video equipment)
-rl level (set report level)
-vm (for video mode)
-vw xmin ymin (location of video window
-nw (for new window for each surface)
-ss (to have all surfaces with same geometry scale)
-nv (to *not* check validity of geometry)

13. …the rest of all per surface: -f geomfilename
-gp geomfilepath (pathname to the geometry files)
-c colour (for mesh)
-cg colour (for vectors)
-ac (leave geometry in absolute coordinates)
-as xmin xmax ymin ymax (to set surface window location)
-ds (make this the dominant surface)
-lm landmarkfile (to read landmark file (eg. coronaries)
-ll leadlinks_filename (links electrode numbers to leads)
-ch channels_filename (links nodes to channels in data)
-cl channellinks_flename (links channels to leadlinks)
-p pot/grad-filename (basefilename)
-ff fidfilename (.fid file to be read)
-fn fidseriesnum (number of the fid series to take)
-dp datafilepath (pathname to the pak-data files)
-s num1 num2 (first and last file numbers)
-i increment (increment between file numbers)
-ps scaleval (scale value applied to all data)
-pl minimum_data_value (user set potential minimum)
-ph maximum_data_value (user set potential maximum)
-cs scale_step_size (user set contour spacing)
-sl surfnum (to lock scaling to another surface)
-t trace_lead_number (for scalar plot)
-at xmin xmax ymin ymax (to set scalar window location)

15. I/O and File Reading Input Output CVRTI ASCII formats
.pts, .fac, .pot, .channels, .tetra, .leadlinks, .lmarks
CVRTI graphicsio formats
.geom, .tsdf, .data, .tsdfc
Output
Same as input for geometry
Image formats (.png so far)

16. Scripting map3d MAP3D=../map3d GEOM=../geom/tank DATA=../data/tank
