[Gate-users] Corrigendum: My mistake in pprevious messaga: Problem running GATE and ROOT with regularMatrix argument

[Simon Stute]

Hi Javier,

Thank you very much for all patches that you sent.
This important bug fix will be included in the next gate version.
But Shahrokh uses the v4 and (I am not 100% sure) and translations and
rotations should work in this version.

Thanks again,
Cheers,
Simon
