1command FINDGAP <trc-list> <outfile> <minzeroes> [<from>  <to>]
2===============

4key: find samples of constant value
5
6Scans the specified traces for sequences of samples with constant
7values (e.g. 0).  Since data gaps are filled by zeroes automatically
8when reading the traces this command will find gaps as well as
9time intervals with ill-conditioned data.
10
11The search will be triggered when it find a sequence of equal to or more
12than <minzeroes> samples of the same value.  The result of the search is
13written to a file <outfile>.

24
25<from>, <to>  ---  parameter type: real
