Besides editing and rearranging the data as described before, INTERACT offers various routines to do even more. All those routines can be found on the Transform tab.
DataSet Time Shifts
For analysis purpose, it is possible to virtually shift the start point of your DataSets.
Those routines DO NOT affect your logged data, but they DO affect the way INTERACT displays your data in the Time Line Chart and therefore how the data is analyzed.
The routines are mainly of interest if you have multiple DataSets in one file. An implementation of this routine, is described in later Synchronize Data for Comparison. A short introduction of the different types is listed right here:
Concatenate - All DataSets are seamlessly joined to a string of sessions. Very helpful, if your session resulted in multiple videos, because you can now visualize your data chronologically. It is a must, if you want to use the Cluster Data Export.
Sync to Code - All DataSets are synchronized on the first occurrence of your selected Code. This helps you to compare what happens before or after this Code was coded over multiple sessions. Especially if you want to compare only a specific interval before and/or after this Code.
Shift to Zero - All DataSets receive a virtual start time of 00:00:00:00. This way all sessions start at the same time, which makes it easier to compare them. Especially if you want to compare the exact same duration for all DataSets.
Remove Time-Shifts - Removes any time shifts entered by the commands above, so everything is back to normal again.
Events
To change the structure of your Events or extract consolidated Events from time sampling based data.
oMerge - Joins Events with identical, repetitive Codes, that were coded in succession within a predefined interval. If you coded for example single Codes, like 'woof', 'woof', 'woof' for every time a dog barked, but now want to transfer this information into durational Events that cover longer periods, which can be labeled with 'Barking dog', this routine is what you need.
•Click Transform - Events - Merge
in the toolbar.
Depending on what you need, pick one of the possible routines:
•Pick
▪> Merge specific successive identical codings if it is only one specific Code you want to merge.
•Select the Class and the Code to merge, from the appearing lists.
or
•Pick
▪> Merge all successive identical codings to merge all repetitions of all Codes in one pass.
In both cases:
•Specify the interval, within which the repetitive Code is considered to belong to its predecessor. Any occurrence of an identical Code, after the specified time frame, is considered to be a new 'barking dog' Event.
Note: This routine also removes (partly) overlaps of the same Code.
oConsolidate - All Events with the exact same time information, are consolidated into one Event, as long as none of the Codes within the same Class differ. This routine is especially helpful if you are using the Time Sampling method (in which all Events cover identical intervals) and multiple raters coded the same video, each rater concentrating on a different type of behavior. Merging this data into a single data-file, results in many duplicate Events. This routine compresses those duplicate Events into a single Event.
oOptimize - Offers routines to get rid of structural inadequacies. Details can be found in Make Data Exhaustive and Make Data Exclusive.
oCreate Coding Segments - Transfers all your codings into a new document in which each combination of co-occurring Codes is represented by a separate Events, as is described in Pattern Segmentation.
Codes
Those commands allow you to:
oChange the case of all of your Codes in one pass
oMove and/or Combine Codes within the same Event, which is explained in Move & Combine Codes.
Time Values
Those commands are discussed earlier in Time Corrections.
