bug in beauti v10.5.0-beta5 Skyride scaleFactor

[evandiego83]

There appears to be a bug when using BEAUTI from the BEAST X v10.5.0-beta5 Prerelease #1d511b10c2. When specifying skyride you get the following error:

SEVERE: 
******
Error in input BEAST XML file, test.xml:
Error parsing '<gmrfBlockUpdateOperator>' element with id, 'null':
scaleFactor must be greater than or equal to 1.0

that is attributed to this:

<gmrfBlockUpdateOperator scaleFactor="-1.0" weight="2">
			<gmrfSkyrideLikelihood idref="skyride"/>
