Error while trying to open a user selected sounding #115

Hello,

While trying to open a .txt sounding I created using and reformatting source data from the University of Wyoming, I encountered the following error.

"zero-size array to reduction operation fmax which has no identity"

This perhaps reveals my status as a neophyte with regards to SHARPpy, but I am unsure of how to proceed. I am using v1.3.0 Xenia on MacOS 10.12.5. I'm grabbing data from here and reformatting it like this.

Hi @1900hurricane ...I've traced the problem to an issue with your data and the MCS Maintenance Probability function that runs in the program. This function looks for data points between 6 and 10 km, and none exist in your data file. This is where the program is choking. I'll implement a fix into the master branch which hosts the Xenia version, but it will only appear in the source code and not the binary version of the program.

Awesome, thank you for your reply. I supplemented the sounding data with a 300 mb height from NARR (9430 m), and that allows it to run normally, fitting perfectly with the explanation you have given.

I just merged #116, so I'm going to go ahead and close this.
