The Java program will write notices and errors to you on the standard output, which may appear in the command or DOS window where you started the Viewmat application. If you get an Out of Memory message, and you are sure that you have entered the right numbers of elements, traces, and planes, then your record is too large for analysis on your computer. 20 megabytes RAM available to the Java application should be enough for one large record. A general rule might be that you will need available RAM of four times the number of bytes in the file. The record will initially appear with default plotting parameters, rather like at right.
Most seismic records have many more time points than traces.
A new Properties window pops up, allowing you to interactively control the plot. If the window panel does not look like the graphic, or if it appears to be missing the lower items, just drag a corner with the mouse to enlarge it a little. Setting the plot parameters correctly for the record will allow you to analyze it more quickly, as some of the geometry information will be correctly set as well. After a moment the record should look more typical, as at right. Once you are satisfied that the record is plotted and labeled properly, and you may be displaying or processing additional records, you can save the plotting parameters in a text file.
