Hi, Josef,

As for the second issue that you mentioned (below), since warpSet itself
returns a flowSet object, it makes sense warpSet(original,
"FL1-H")$flowset would return NULL (see the value section in warpSet's
man page). The correct way is to get the resulting flowSet object is:
obj <- warpSet(original, "FL1-H")

To view the result, do
densityplot(~`FL1-H`, original)

Sorry for the delay of my response.

>>> Issue 2, no error but returns NULL:
>>>  > warpSet(original, "FL1-H")$flowset
>>> Estimating landmarks for channel FL1-H ...
>>> Registering curves for parameter FL1-H ...
>>> NULL
