Switching between OP families is a very powerful tool, but it can sometimes be a very resource-consuming process (especially a TOP-to-CHOP conversion if Download Type is switched to immediate (slow)). Of course, it's important to be aware of the possibilities of conversion since certain operations on data are often difficult in one domain and straightforward in another; therefore, even switching back and forth can sometimes make a lot of sense. You'll find COMP at /project1/05_OPconversion if there are a couple of example conversions. Sometimes, data needs to be prepared in a certain way for the conversion to work. For example, CHOP data needs to be in the range of 0 to 1 for a conversion to TOP, and DAT needs to have certain titles in its first row to tell DAT and SOP which column means what. You'll find two OP family full cycles, so go through all the families until we arrive at the family we started at. One of them is depicted in the following screenshot...
