One way to do this is to explode all attributes to features, merge and count the results.

• AttributeExploder to create features from all attributes.
• AttributeFilter to filter only features where value is true or false.
• Aggregator to merge and count all features grouped by row id and attribute value.
• FeatureMerger to merge the results back to the original values on row id.

If all the attributes with true and false values end in ZTF I would use a ListExpressionPopulator with a Source Attribute Expression of ZTF$ to get all the true false values in a list, followed by a ListHistogrammer which will then count the true false occurrences and return the results in a list

You can then turn the list values into attributes

thank you all it works :)
