Warning in Check_Performance_Cutoffs() :
Low trial count: 1 (cutoff is 240)

Error in if (analysis$stats$hit_percent < user_settings$minimum_hit_percent) { :
missing value where TRUE/FALSE needed

Possible solution:

1. skip entering single trial files - most likely in which case no code change needs to be made.
2. bypass doing stats calc for files like this.

Probably just need to check that type 1 trials are > 0, otherwise bail out of stats calc with warning "Too few trials to calculate stats"

But need to watch out for the gotchas that:

• some files have no type 0 trials (e.g. some of the Oddballs)

Note that #30 is also a bug primarily caused by low trial count. Not sure if there's a universal fix like not importing data with fewer than 20 trials or something.
