RangeModel support starts with the RangeModel User's Guide, which should answer most of your questions. If you have a question about input formats, check the instructional menu items in the Import menu.

Please do not telephone the Author with support questions.
If RangeModel does something you did not expect, first try consulting the RangeModel User's Guide, to see if the behavior is normal. If something happens that is clearly not intended, you may have found a bug. If a 4th Dimension error window appears, you have definitely found a bug.
The 20-randomizations Bug. When you use the Compute Confidence Intervals tool, you must avoid requesting exactly 20 ramdomizations. If you so so, the procedure never finishes and the exported output contains nonsense. Any other number is fine (including 19 and 21!). This bug has been stubbornly resistant to resolution, as it is caused by a faulty 4D progress indicator.
RangeModel's current tools and features evolved over a period of 6 years, partly under the guidance of RangeModel users. Suggestions for improvement are welcomed. Please include the word "RangeModel" in the Subject line of your message.
