AltAnalyze v.2.0.7 crash - local variable 'log_fold' about altanalyze HOT 1 CLOSED

This problem is almost always caused due to an issue with how the exon and 
junction files are named. AltAnalyze must match up each exon and junction file 
that correspond to a single sample propperly, or this error will occur. An 
example of a valid pair of files names is "patient1__exon.bed" and 
"patient1__junction.bed". A bad example is "patient1_exon.bed" and 
"patient1_junction.bed", where only one and not two underscores are used. The 
text "exon" and "junction" here are not important (anything can be used 
following the __ and AltAnalyze automatically detects exon versus junction 
files based on the number of columns in the file). Rather, the identical sample 
name preceeding the double underscore must be present. In the next version of 
AltAnalyze (versoin 2.0.8), this problem will be caught before the analysis is 
run.
