Hi

to filter features with  specific names , we can use featurenamefilter but how?
for instance I want to filter all feature except the following features:

Volume, Surface, information*var   (-> here * is as a wildcard)


thanks

    hi  again:
    my features names which I want to save them are:
    CV.INFO_CORR2
    VOLUME
    CV.ENTROPY
    CV.INTENSITY.1

    and I used  following parameters:
    <parameter key="skip_features_with_name" value=".*"/>
    <parameter key="except_features_with_name" value="CV.INFO_CORR2 || VOLUME|| CV.ENTROPY||CV.INTENSITY.1"/>

    first line works , but 2nd line nooooooooooooooooooooo >:(
           
    also  I checked following wildcards
    |.  and |


    but again noooooooo
