comment Speeding up TIF import
6000 should be around 9 GB and 50,000 around 73 GB. It's huge, but it should fit. However, I can imagine that it needs extra temporary memory while loading and unpacking. It's also possible that it uses temporary files too. That will take quite some time in this case. Perhaps it can be saved as a raw binary?

comment Why doesn't FindRoot work correctly?
x - 0.25*Pi*Cot[Pi*x] is the expression that you want to set to zero for a certain x. FindRoot finds this x. If you now write x - 0.25*Pi*Cot[Pi*x] /. FindRoot[...] the found value of x is filled in in the expression and you see that it is indeed (close to) zero.

Indeed, put x - 0.25*Pi*Cot[Pi*x] /. in front of each FindRoot and you'll see it has found a correct root.

comment Techniques Modifying Cells M8.0
But Cells in v9 returns completely different objects as in v8 with your Cells function, so I guess usage further on will differ considerably too.
