This potential issue (see release notes) has been fixed in this minor update and integrated in the 1.10.4 installer. If you had already installed version 1.10.4 build 1248, we recommend to re-install the updated installer to avoid this potential issue.

• 27 JUL 2008  RFX-GLM bug affecting between-subjects ANCOVA analyses. A severe bug has been detected when calculating between-subjects ANCOVA models for the case that these models were based on RFX-GLMs as input. The bug could be localized within the RFX-GLM routine, which was updated for version 1.10.2. The bug was not detected during testing, because it affects only subsequent between-subjects ANCOVA models if these are based on RFX-GLMs. All values used for statistical assessment of RFX-GLM contrasts were calculated correctly. This problem did not occur when calculating standard separate-subjects GLMs; the issue did also not affect any ROI-GLM-based ANCOVA results, and it did not affect any ANCOVA model using VMP or CMP data as input.
  Solution: Update to version v1.10.3 using automatic web update and recalculate RFX-GLMs in case that you used them as input for ANCOVA models with between-subjects factors.
