SAS watchout

When the task emosaic_prep is run, it gives the following error:
Cannot exec "preqgti": No such file or directory at...
How to fix this problem?

The current version of emosaic_prep makes use of a new task preqgti to calculate the XMM-Newton stable pointings GTIs. This task was not included in SAS 14.0.0, therefore if you need to run emosaic_prep, please download and install preqgti-0.7.2 from here.
