If your coding system, does not consist of sequential and exhaustive codes, INTERACT offers some nice features that give you information about the NOT CODED parts of your session. Those not coded parts are referred to as gaps.
Gap Statistics
The DataSet based Statistics do offer various values about those Gaps, that might be of interest:
oGap Count
oGap Duration in Seconds
oGap Minimum Duration
oGap Maximum Duration
oGap Mean in Seconds
oGap Geo Mean in Seconds
oGap Harm Mean in Seconds
oGap Duration Variance
oGap Duration Standard Deviation
If those values are not available, within the results of the Full Statistics or the Statistics per DataSet, all you need to do, is to select the corresponding items in the Timeline Chart options on the Statistics tab.
Create Events for all Gaps in a Class
While coding, the resulting Event might hold gaps and/or overlaps for different reasons:
oNo Code available for every situation
oUn-coded sequences because of irrelevance
oEvents coded without applying the Log Mutually Exclusive Codes feature properly
oSkipped frames due to video controllability issues
o...
I many cases, gaps and overlaps are just fine, but in other situations you might need to make your data exclusive (no overlaps) and even exhaustive (no gaps).
INTERACT offers some powerful features to resolve most systematic issues afterward with a single command. Explore the available routines, depending on your situation:
 | Add Missing Events - To add new Codes in new Events to fill in the blanks between existing Events, use the routine described in Add Missing Events. |
| Close Gaps - To close (usually tiny) gaps between existing Events, without adding new Events and Codes, use the routine describe in Close Gaps. |
| Make Exclusive - To get rid of unintentional overlaps, use the routine described in Make Data Exclusive |
Gap Statistics
Additionally, INTERACT offers plain descriptive Gap-statistics to count the gaps around each Code, even without creating Codes for these gaps.

Contingencies
The Contingency Analysis also offers the possibility to fill gaps between two specific codes, whenever the distance between those two Codes does not exceed a specific time range.
