What it does
============

Allows to manually set the data types of metadata. `ampvis2: load` tries to
detect the metadata data types automatically. If this is not as desired
the data types can be set manually with this tool.

Input
=====

@HELP_RDS_INPUT@

@HELP_METADATA_LIST_INPUT@

Output
======

**RDS**

The main output of the tool is an RDS data set that contains the R representation of
the ampvis2 object containing the same data as the input, but with data types changes
as chosen in the input form.

**Metadata list file**

Updated metadata (only column 4 should change and reflect the desired datatype changes).
