I am using ImageMiner-1.4.1 extension.   When using  the Local Feature Extractor is get this message:
"ExpectedImagePlusGSIOObject but received ImagePlusBaseIOObject".  Look the process below.

I think that indeed maybe there has been some kind of change between the versions.
Check this workflow http://www.myexperiment.org/workflows/2324.html where  Local Feature Extractor  works fine.
If this is not the way to use the  Local Feature Extractor anymore that what could be a way, since there is not way actually to use this operator.

Thank you in advance.

Best,
Elena
