Description
Hi,
5.3 rotconverter's behavior is different from 5.2.2.
For example, using 5.2.2 the following line works:
rotconverter BAL-EUR EUR-NAM
It doesn't for 5.3 any more (
rotconverter EUR-NAMworks though).
Sincerely, Chenjian

Aren't you missing an operator? You need a plus or minus between those two rotations.

Hi Paul,
Thanks for your reply. So here to calculate rotations for Baltica relative to a fixed North America using the plate circuit Baltica-Europe-NorthAmerica, based on a rotations database, as the last example shown in the rotconverter doc, it can be
gmt rotconverter BAL-EUR EUR-NAM. I also tried
gmt rotconverter BAL-EUR + EUR-NAMin 5.3, but still this
rotconverter: Error: Could not find rotations for the plate pair BAL - EURpops out. In 5.2.2, it works since there is indeed rotation data between BAL-EUR, although for younger times BAL and EUR are fixed to each other.
Sincerely, Chenjian

Just a side note to clarify that there are not (yet) GMT5.3 and there was never (nor will be) a GMT5.2.2 versions.

Just to confirm that the BAL-EUR is in the Gplates table but it is a null rotation:
302 0.0 0.0 0.0 0.0 301 !BAL-EUR Baltic Shield-Northern European Craton 302 231.0 0.0 0.0 0.0 301 !BAL-EUR
and I think rotconverter (now) skips null rotations. I will have a look. Meantime you just ignore using BAL-EUR since it would do nothing.

We now allow null-rotations to be loaded again. In r17215.
