Author Topic: Local Feature Extractor Problem  (Read 355 times)
« on: July 03, 2013, 11:56:29 AM »

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 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.
