The Daily Dongle

heads up, changing hosts

Effective June 1st, my next billing cycle here, I'll cancel my typepad account and move the blog over to MyCyte.org, which is TreeStar's attempt at Flow Oriented Networking and Contenet (FONC). Retention or all DD posts is my primary concern so until this site is fully mirrored - nothing will be taken down. I'd like to invite anyone else interested in flow blogging or forum-ing to also join me in supporting mycyte - it's free.

It'd be cool if DeNovo and Verity and whomever else wanted would start their development and support-oriented blogs all in one place.

inverted values

I've occasionally done this as a prank - but today I've had fun testing some CXP data while inverted. On a mac with OSX, you can do this with the four-key-combo: ctrl+shift+cmd+8 - which can be used again to restore normalcy. We should put more custom gradients into FlowJo. Apophysis XML based gradient scheme comes to mind.

hacking polyvariate platform for precise controls

If you've ever used the polyvariate platform, you might have noticed the only way to control it is with your mouse, which is imprecise.

if you would like full hands-on control of the PV platform, save your FJ workspace as XML (file/save as xml) and look for these snippets:

<VectorTransformation VectorPivot="0.25" XMin="0" XMax ="1" YMin="-1" YMax="0">
<VectorDefinition Parameter="FSC-A" Pivot="0" XFactor="1" YFactor="0" />
<VectorDefinition Parameter="SSC-A" Pivot="1" XFactor="0" YFactor="1" />
<VectorDefinition Parameter="&lt;FITC-A&gt;" Pivot="0.25" XFactor="0" YFactor="-1" />
<VectorDefinition Parameter="APC-W" Pivot="0.25" XFactor="-1" YFactor="0" />
</VectorTransformation>

the top level element variables are the radius of the circle (out of 1 max), and positions of the X and Y axis sliders.

all of the subsequent elements show three variables: the pivot point, and the magnitude of the radial vector expressed in X and Y components: (1,0) is 3 o'clock, (0,0) is the origin, (-1, -1) is a median between 6 and 9 o'clock

You can change the values for each attribute, save your .xml, rename it to .xml.jo and re-open in FJ.
