I'm trying to reproduce a FlowJo workflow in flowCore. I received a description of the FlowJo biexponential transform settings from my colleague, which are:

```
# Minimum is -1622.427; -10^3, no extra negatives
# Maximum is 262144; 10^5
# Width is -100.
```

The `flowCore::biexponentialTransform`

function has the following call:

```
biexponentialTransform(transformationId="defaultBiexponentialTransform",
a = 0.5, b = 1, c = 0.5, d = 1, f = 0, w = 0,
tol = .Machine$double.eps^0.25, maxit = as.integer(5000))
```

And the usage documents don't further elaborate on these parameters.

The `logicleTransform`

function has parameters with values closer to the FlowJo ones:

```
logicleTransform(transformationId="defaultLogicleTransform", w = 0.5, t = 262144,
m = 4.5, a = 0)
```

Here m=4.5 looks like the 5 decades that I have and t= 262144 matches my maximum. So maybe I should be using `logicleTransform`

instead of `biexponentialTransform`

. But if so, I'm not sure what values to use for `w`

and `a`

. I did try picking some reasonable values (w=0.8 and a=1.0), and my plots come out similarly to the FlowJo plots, but the transformed values end up still being somewhat off, so I'm still not quite there.
