Comment: C: Problem parsing data with parseWorkspace
... Your workspace was produced by `FlowJo` version 7.6.5, which handled Logicle transformations significantly differently. I took your workspace and loaded it in to `FlowJo` version 10.6.1, which itself raised a dialog box to emphasize the changes since the old version: "This workspace has one or more ...

Comment: C: Problem parsing data with parseWorkspace
... 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 at `Log FL 1`) which makes me think there is something ...

Answer: A: custom gatingMethod not functioning / registering as expected (openCyto) (minDen
... I'll gladly look in to your function quickly to see what the issue might be, but have you also checked out `tailgate` (it will be renamed `gate_tail` in the upcoming API changeover). It uses the derivative of the KDE to handle this situation (one peak, so no valley). One of the vignettes briefly tou ...

Answer: A: flowCore issue: creating and applying new compensation matrix
... Hi @riedel. As the error message says, the matrix you are trying to use for compensation is not invertible (in other words, it's "singular"). The compensation calculation requires that the matrix be invertible, so the `compensate` method is appropriately failing. In this case, starting with a zero ...

Answer: A: Issue creating transformed filter in flowCore
... You can do this using a `transformList`, which is discussed a bit in the package vignette. Additionally, `logicleTransform()` will give you default transformation parameters, but you should look at `estimateLogicle()` to estimate these for your data. Anyway, try this (adapted from your code): ``` # ...

Answer: A: Convert Flowframe to matrix
... Do you just want the matrix of the measured intensities? If so then the `exprs` method will extract that slot. So, if `fr` is your flowframe, `exprs(fr)`. ...

Answer: A: how to use the flowCore spillover function
... There are a few different issues at play here. First, your error is coming about from a simple typo. The argument to specify the forward scatter parameter is `fsc`, not `fcs`. Second, you can only specify a single column name for each scatter parameter, not a vector of names. That is, you have this: ...
