What is the occurrences parameter?

The occurrences parameter refers to the minimum number of instances in the data set a motif should occur. If you have an enormous data set of thousands of proteins, you may want to set the occurrence threshold high (at say 50) to get generalized motifs. On the other hand, if you are looking for a motif in only a handful of proteins, chances are no single motif occurs 50 times, so you will probably want to set a low occurrence threshold (maybe 5 or so).
