Observer 4 data:
You need both the *.odf data file as well as the corresponding *.ocp config file.
▪Click Start - File - Open 
.
▪Select the Observer 4 data file (*.odf) and click Open.
▪Select the config file (*.ocp) in the next dialog and confirm.
Observer 5 data:
Because the data structure has be completely reworked, the old routine does not work anymore. That is why you first need to export your observer data into a text file, from within the Observer. If you have exported your data, do as follows:
▪Click Start - File - Open .
▪Select the exported Observer *.txt file and confirm.
In both cases, the imported data contains a 'Subject' and a 'Behavior' column (now referred to as Class) and the comments are entered into the Transcription area of the corresponding Events. Each Event receives an start time and an offset, based on the Observer Event type (State start/ State stop).
Note: If your data is not interpreted correctly, send us an export file and a description of the problems that occur with it, so we can adapt the import routine.
Observer 11 data
Once again, the export format has been changed:
▪Export your data using the command Export - Observational data...
▪Verify that your exported txt file has the following columns in this order in its header:
o'Date_dmy'
o'Time_Absolute_hms'
o'Time_Relative_hmsf'
o'Duration_sf'
o'Observation'
o'Event_Log'
o'Subject'
o'Behavior'
o'Event_Type'
o'Comment'
▪Back in INTERACT, Click Start - File - Open .
▪Select the exported Observer *.txt file and confirm.
Note: The structure of the exported Observer files is rather limited, providing only one subject column and one behavior column. To make the most of your data during analysis and make use of the full power of INTERACT, you should restructure the resulting data using the following commands:
- Use the Move & Combine Codes command to move Codes to new Classes, to split-up behavior per type with just a few mouse clicks. - - Restructure your data into separate Sets per Subject as described in Split Events into Separate DataSets, based on the 'Subject' column to easily get subject-based statistics and maybe use the State-Space-Grid.
