MCMCTree "Error: File Name Empty"

[Michael Forthman]

I've performed MCMCTree with usedata = 3. I now have my in.BV file in a separate directory, with the alignment, tree, and control files copied in the directory as well. I changed the control file usedata = 2. When I ran MCMCTree I got a very uninformative error message "file name empty". My log file shows that MCMCTree read each DNA partition and the fossil calibrations I used; the program suddenly stops after reading the fossil calibrations with no other error message or details.

I solved my problem. I'm suppose to indicate the input BV file in the usedata option, i.e., "usedata = 2 in.BV". I figured this after looking at some example files. If this was in the manual, it was pretty well hidden.

Cheers, Michael

usedata = 2 inBVfilename specifies the approximate likelihood calculation, with the input (gradient & Hessian matrix etc.) in the file.

the doc has this line but it happens to be on the next page. i'll edit the text a bit to make this clearer.
