I agree Thomas makes good points. But I prefer to try the software myself. The X-Trans raw has to be one of the most frustrating formats to democaic that I have ever worked with. I have been using the new Iridient conversion that takes the RAF to DNG then opening the dng's in LR. The ON1 option is just another way to work. They give you a free 30 day trial full function, so it's worth looking at IMO. The ON1 interface is strange if anything, but the conversion that it can make on the X-trans is impressive at least for me. Takes a bit of time to figure out the best settings.
It's very close to Iridient's but ON1 has a much better tool set i.e. adjustment layers, ND filters etc.
