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)

…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)
