Introduction to CSLICE

Last Release: November 3, 1998

cslice is a MATLAB tool designed for easy visual interrogation of ECOM NetCDF files. The name cslice sort of stands for cross-slice. Not a great name, but it kind of stuck. Plus, there were already matlab routines called islice, jslice, kslice, etc., from the ECOMviz matlab package, that allowed the user to cut along the i, j, and k directions. However, cslice is somewhat more general, in that the user has interactive control over how they want the data set to be sliced, including horizontal and any orientation of vertical slicing.

cslice builds upon ECOM interrogation routines written by Rich Signell, and allows the user to

• vertically slice the data.
• change the resolution of the vertical slice.
• save a figure window to a MATLAB *.m file.
• save the window data to a MATLAB *.mat file.
• print the window to postscript or encapsulated postscript.
• change the current variable to another such variable in the data set.
• change or edit the colormap.
• change the shading.
• overlay the horizontal slice with the velocity field.
• zoom in on a particular area of interest.

Known Problems

On 32-bit SGI machines, cslice will not work with SCRUM files. There is a bug in mexcdf causing this.

If you encounter any problems, please email me at rsignell@usgs.gov. Include as many of the error messages as your system feels like giving you, and your particular version of MATLAB as well.

Release Notes

• Renamed linterp function to avoid name clash with robust toolbox.
• March 12, 1998. There were problems when users deleted any windows without using the "hide" or "exit" callbacks properly. Circumvented.
• April 21, 1997. Rewritten to take advantage of MATLAB 5.0.
• November 4. Changed print option to handle Postscript Level 2. Printing to a file now results in a file dialog box popup.
• June 28. Double-clicking on the same mouse point was confusing it. If the second mouse-point is the same as the first, it is now ignored.
• June 26. Arrgghhh! When previous problem "fixed", made a mistake with RCS that caused further crashes. Fixed.
• June 25. Problem noted that if data min and max are both zero, assigning a color axis will fail. Fixed.
• June 12, 1996. Initial Release!
