RAW digital photography formats are not converted between each other, and there is probably no program that could do it anyway. RAWs are generally either exported to a digital negative (DGN), or as plain picturer export to JPEG/TIFF format.
This conversion entry was verified by us and conversion from mrw to raw was flagged as wrong or not possible.
Usually this happens when the conversion would try to convert different types of data between each other, such as audio to image, or it is not possible because incompatibility between programs, caused by closed file formats, very limited support etc.
If you find entry that you feel is flagged as bad wrongly, please tell us in the discussion below with as much as information as possible so we can fix it.
