'dimension mismatch' error

[niemasd]

I ran LogDate using dates.txt and tree.txt and got the following:

Launching LogDate version 1.3.1
LogDate was called as follow
/home/niema/.local/bin/LogDate.py -i tree.txt -t dates.txt -o dated.txt

My sample dates are in unit of days since 0001-01-01. Thoughts?
