Validation Run Failure

[warnke]

Trying to set up DCEMRI on linux box for testing. Previously, I received PyPlot not installed warnings, which led to results not being stored. After adding PyPlot Pkg.add("PyPlot") and using PyPlot, I run
validate(6, "/home/ubuntu/temp/"), but then get the following error:

Noisy data saved to /home/ubuntu/.julia/packages/DCEMRI/IqKLJ/src/../test/q6/qiba6noisy.mat

Line 87 of validate.jl: 
`figure(figsize=(4.5,4.5))`
seems to be throwing the error

However, in julia repl, after `using PyPlot`, 
```>>> figure(figsize=(4.5,4.5))```
`Figure(PyObject <Figure size 450x450 with 0 Axes>)`

Thanks for your help!

Was the package installed from the registry?
I think that version is a bit out of date.

Try installing from the master branch

]add https://github.com/davidssmith/DCEMRI.jl.git#master

and hopefully that'll scare the errors away.

• no more errors after upgrading to current master
• I greatly appreciate your quick help @notZaki

This is excellent news. I was just sitting down to look at this. Thank you, @notZaki
