Deprecation notice

The 1.0.0 version of Glotaran was released more than 13 years ago, and the creators of Glotaran think it's time for a change. For the past few years they have been working on a successor for Glotaran, re-written from the ground up in Python, called pyglotaran. Please check it out!

In conclusion, I find Glotaran to be a highly useful and capable addition to my analysis toolbox. The authors of the program are very helpful and communicative, and I have no doubt that Glotaran will continue to gain in features and ease-of-use. If, after reading this review, you have the slightest hunch that it could useful for you, download it and give it a go. I doubt you will be disappointed.
