I installed PI on UBUNTU 12.04 under a trial license.
After the installation PI proposed an updating which I accepted.
At restart of PI the updating took place, but an error was indicated on Intensity Transformation, and some processes disappeared (Histogram Transformation, STF, Curves Transformation...).
I tried twice the installation with the same result.
To have available the processes missed I unchecked the updating of Intensity Transformation to module version 1.5.1.193.
Now the PI core version is 01.07.06.0793 Starbuck (x86).
Thanks for any help,
Fabrizio
