Hi,

I'm running Ilastik 1.2.0. When I try to select features in object classification I get the following error message

Python argument types in
    vigra.analysis.extract2DConvexHullFeatures(VigraArray)
did not match C++ signature:
    extract2DConvexHullFeatures(vigra::NumpyArray<2u, vigra::Singleband<unsigned int>, vigra::StridedArrayTag> labels, boost::python::api::object ignoreLabel=None, bool list_features_only=False)
 (Advanced information about this error may be found in the log file: /home/abrown/ilastik_log.txt)

Is this related to an undocumented requirement or is it a bug?
I can send the log file if that's useful.
Running Ubuntu 16.04

We are planning a new release later this week, this problem should be gone.

Is there a new release available somewhere already? We just stumbled upon this very same issue as well 🙂

TrackingFeatureExtraction: do no overwrite inputslot value depending …

…on data shape. Adresses #1432 in tracking workflows.

Overwriting the list of pre-selected features for tracking depending on the raw shape is too restrictive.
If the user first loads a 3D dataset but then, by adjusting the axestags, changes that to 2D+t, the 2D features should become available again.
If the feature slot value is overwritten but the original value is lost, this cannot be recovered. Hence here the initial value is
stored as member variable of the operator, and the input slot is overwritten with the correct value.
