[Announcements] bug report

[xli at mristudio.org]

Dear MriStudio / DtiStudio users,

Recently we found a bug in our automated white matter parcellation report in
ROIEditor which was downloaded before 12/21/07.

Here is the symptom:

If images are normalized to ICBM-DTI atlas and loaded to ROIEditor for automated
regional analysis, following results are obtained:

ICBM_MNI_FA

In this report, there is one-row shift from #7 CST-R to #21 RLIC-R. The
corrected version should provide,

ICBM_MNI_FA

If you choose Talairach or JHU-DTI atlases, they are not affected by this bug.


Please let us know if you have any questions.
