When I try to parse .wsp workspace data I get the following Error:
Error in .cpp_gating(gs@pointer, mat, guid, gains, nodeInd, recompute, : ellipsoidGate::transforming can’t find transformation for FL 4 Log
Loading the workspace seems to work fine and all samples can be loaded via the flowCore package with no issues. Is there something that needs to be changed inside of FlowJo (it seems to be a gating issue) to make it work with the flowWorkspace package?

It's a little hard to say without seeing the workspace. Would you be able to provide me with the workspace file somehow? Email would be fine: jpwagner@fredhutch.org. It seems strange that it would error out at
Log FL 4(rather than right away atLog FL 1) which makes me think there is something wrong with the workspace file itself.I can get the FCS files from FlowRepository, so don't worry about those.
Your workspace was produced by
FlowJoversion 7.6.5, which handled Logicle transformations significantly differently. I took your workspace and loaded it in toFlowJoversion 10.6.1, which itself raised a dialog box to emphasize the changes since the old version:"This workspace has one or more parameters using the Logicle transform. Because the implementation of this transform has been updated, any gates on these populations will need to be adjusted."
Sure enough, the gates were off for Logicle-transformed channels, but I still re-exported it to see if
CytoMLcould handle the re-exported XML.CytoML::parseWorkspacecan indeed parse the re-exported XML, but it has the same issue asFlowJo10.6.1 of misplaced gates due to the change in the Logicle transform, so those will need to fixed.I am not sure when we will have a chance to devote time to this backwards compatibility, but I will post here when progress is made on that front. For now I will e-mail you the re-exported workspace XML that is
CytoML-compatible.Thanks a lot for the support! The re-exported workspace loads with no issues. Luckily we just switched to the newest version of FlowJo so this shouldn't be a problem for us in the future.
