Summary

0001355: Mintime only calibration sometimes gives an error

Description

There seems to be a problem with the mintime only option. I have done a few tests (see attached file).

Steps To Reproduce

Reltime-ML
Use mtCDNA.meg and mtCDNA.nwk as input files; options other than calibrations: Tamura-Nei model, Uniform rates, use all sites, threads=4
Select gibbon as outgroup (select branch)
Select constraints:
a. Single calibration, Fixed time, human-chimpanzee at 6.00, click ok  no error
b. Single calibration, Uniform distribution, human-chimpanzee at 5.00-7.00, click ok  no error
c. Single calibration, Exponential distribution, human-chimpanzee at offset=5, lamba=0.250, click ok  no error

d. Single calibration, Mintime Only, human-chimpanzee at 6.00, click ok --> error
e. Single calibration, Maxtime Only, human-chimpanzee at 6.00, click ok  same error as in case d
f. Two calibrations:
a. First one: fixed time, human-chimpanzee at 6.00
b. Second one: Mintime Only, chimpanzee-gorilla at 8.00, click ok  no error at this stage. Proceed to set other options (see above) and launch analysis  it starts but soon exits with an error
g. The analysis runs correctly if I keep everything as in point f but switch the order of the two calibrations (first: mintime only human-chimp=6.00, second fixed time chimpanzee-gorilla=8.00).

h. The analysis runs correctly if I keep everything as in point f but change the second calibration to an exponential distribution with offset=8.00 and lambda=0.250

i. Two calibrations:

     a. First one: Mintime only, human-chimpanzee at 6.00
     b. Second one: Mintime only, chimpanzee-gorilla at 8.00 -->Error
j. Two calibrations:

     a. First one: Exponential distribution, human-chimpanzee offset=6.00, lambda=0.25
     b. Second one: Exponential distribution, chimpanzee-gorilla offset=8.00, lambda=0.25
This analysis runs correctly.

Additional Information

I have screenshots of the errors but cannot upload the file because it is too big. I can email it, if you would like.
Thanks!
