[Bioc-devel] flowCore 1.22.0 broken for some FCS files (which it previously read without errors)

Hi Kieran,

I'm not really familiar w/ flowCore at all, but just wanted to note that:

This isn't your only option -- you don't have to "downgrade" per se.
If you're really in pinch, you can install a previous version of R
*along side* your current install and simply install
biocLite('flowCore') to take a crack at your data.

In the best case, you could just save the binary file and reuse it in
a newer version of R/flowCore -- worst case is that you just run the
analysis on your older R install (I admit, not ideal but ... ).

Alternatively, if your input file isn't a binary one it probably
wouldn't be *too* cumbersome to debug what's causing the problem by
tracing through the offending function to whip up a fix, especially if
you have both versions of flowCore (new/broken and older/working) side
by side.

If it is binary, though, I can certainly appreciate how that might be
a stretch too far.
