NeXtMidas User's Guide: Type 2000 Files

Type 2000

Type 2000 files contain a two-dimensional array of data values, such as an ambiguity function or power spectra versus time. The file is organized into frames, each of which looks like a Type 1000 file. A Type 2000 file is simply a stack of frames where each frame corresponds to the x-dimension and is stacked in the y-dimension. The header describes both the physical abscissa information for the frame, and the physical ordinate (y-axis) information for the stack:

physical abscissa (frame) units
physical abscissa (frame) starting value
physical abscissa (frame) increment
frame length
physical ordinate units
physical ordinate starting value
physical ordinate increment

Advanced Capabilities for Type 2000 Files

Plotting Multiple Rasters on a Single Plot

Use CONVERTARGB with /ALPHA0COLOR to convert each raster file to DirectColor file. If the /ALPHA0COLOR is not specified, it is assumed to be BLACK.
- convertargb IN=psd1 OUT=raster1 MIN=0 MAX=32 ALPHA=200 COLORMAP=cmap32 /ALPHA0COLOR
- convertargb IN=psd2 OUT=raster2 MIN=0 MAX=32 ALPHA=200 COLORMAP=cmap32 /ALPHA0COLOR
Plot the rasters specifying them as Direct Color files
- plot raster1{LAYER={DC=true}}|raster2{LAYER={DC=true}} /type=raster XMIN=0
