Parameters
ssFilter is a scalar string that specifies the record filter. The filter can consist of up to four AND (&&) or OR (||) connected comparions. Each consists of an in $ character enclosed channelname, followed by an operator followed by a value. See example. The following operators are available:
| Operator | Meaning |
|---|---|
| Channelname < Value | True if Channelname is less than Value. |
| Channelname <= Value | True if Channelname is less than or equal to Value. |
| Channelname == Value | True if Channelname is equal to Value. |
| Channelname != Value | True if Channelname is not equal to Value. |
| Channelname > Value | True if Channelname is greater than Value. |
| Channelname >= Value | True if Channelname is greater or equal to Value. |
ssNCName is the complete name of an NC-Data file. This parameter is optional, if the auto_ImportData() has been called before auto_SetFilter.
Example
auto_ImportData(GetRootDirectory() + "samples/vollast.asc");
auto_SetFilter("$N$ > 1000 && $N$ < 5000 && $MEFF$ >= 100");
