Download GSEQ et al.

  • Download GSEQ51Setup.zip from Georgia State University, USA. Unzip and run GSEQSetup.exe.
  • Download GSEQ 51.exe from Universitat de Barcelona, Spain. Run GSEQSetup.exe.
  • Running the setup file installs the program. Thereafter, to run GSEQ, click Start > Programs > GSEQ5 > GSEQ 5.1, or click on the GSEQ desktop icon.

GSEQ iconGSEQ Version 5.1 includes new algorithms for computing interobserver agreement, both for event and timed-event sequential data, which are described in:

Bakeman, R., Quera, V., & Gnisci, A. (2009). Observer agreement for timed-event sequential data: A comparison of time-based and event-based algorithms. Behavior Research Methods, 41 (1), 137-147.

Quera, V., Bakeman, R., & Gnisci, A. (2007). Observer agreement for event sequences: Methods and software for sequence alignment and reliability estimates. Behavior Research Methods, 39 (1), 39-49.


ActSds (Mangold’s INTERACT to SDIS converter) converts Mangold’s INTERACT data files, various versions, into SDIS files that can be subsequently analyzed by GSEQ. For information about INTERACT, visit  Mangold-International.com.

ObsTxtSds (Noldus’ The Observer to SDIS converter) converts Version 6 and later Noldus’ The Observer data files  into SDIS files that can be subsequently analyzed by GSEQ. For information about The Observer, visit Noldus.com.

ActSds and OdfSds (an earlier version of ObsTxtSds) were described in:

Bakeman, R., & Quera. V. (2008). ActSds and OdfSds: Programs for converting INTERACT and The Observer data files into SDIS timed-event sequential data files. Behavior Research Methods, 40 (3), 869-872

The ZIP files contain the executable file, either ActSds.exe or ObsTxtSds, and a PDF file describing the program.


ELign: A standalone program for aligning event sequential data by means of dynamic programming algorithms, and computing an alignment kappa. Note that the ELign algorithm is included in GSEQ 5 as well; using GSEQ 5 for aligning event sequences and computing Kappa is easier than using ELign. Eligin is sescribed in:

Quera, V., Bakeman, R., & Gnisci, A. (2007). Observer agreement for event sequences: Methods and software for sequence alignment and reliability estimates. Behavior Research Methods, 39 (1), 39-49.

The ZIP file contains the executable file, Elign.exe, plus several sample SDIS data files.

All programs were written in Embarcadero® Delphi® XE2 Version 16 Pascal and run on a PC under Microsoft Windows or a Mac running a PC simulation program.
