            Bug ID: 1086
           Summary: ClassCastException when using Process>Batch>Convert...
           Product: Fiji
           Version: unspecified
          Hardware: PC
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P4
         Component: Plugins
          Assignee: imagej-bugs at imagej.net

When trying to convert a folder of czi files to TIFF using 'Process > Batch >
Convert...', the exception below [2] is thrown. The czi files contain
hyperstacks of 3 channels and 19 z-slices and they open correctly when opened
normally (i.e. via drag-and-drop or using the Bio-Formats Importer).

A workaround is to use 'Process > Batch > Macro...' and entering just an empty
comment ('//') into the macro text field.

Looking at ImageWriter.java [1], it seems that the nImages<=1 for the
associated FileInfo opbject.

Cheers,
Jan
