Research software

Your workplace is equipped with a standard basic software package. In addition, you can also install various additional applications or language packs via (Managed) Software center.

Is your software not available via (Managed) Software center? Send a request via the helpdesk portal. Your application will be assessed by your ICT contact person.

SOLO Research and Lab Support provides support to researchers for the software packages described here, unless stated otherwise. A basic level of experience with the software is expected. SOLO Research and labsupport does not provide in-depth support to students. However, in case of urgent (software related) lab issues, SOLO can be contacted.

The following software is installed on all lab computers:

  • E-Prime 2 and 3 including EET 2 and 3
  • Python 3
  • Biopac AcqKnowledge
  • Biosemi ActiView
  • Tobii Studio

To request for software to be installed on a lab computer other than the list above, please contact SOLO Research and Lab Support.

To request for software to be installed on your work computer, install the software through the Software Center or apply for the software at the ISSC.

Please note: Do you want to use software we don’t offer and/or support? You or your research section may have to finance this from your own research budget, and support will be limited. If more researchers or groups want to use this new software, financing possibilities are available. For more information, please contact SOLO Research and Lab Support.

Stimulus software is used for experiments in which stimuli like pictures, movies, sound, itch, and pain are provided and responses are measured. Often it is combined with physiological measurements or eye tracking experiments. Software for online surveys is also available.

Tobii Studio

Tobii Studio is software used in combination with a Tobii eye tracker. It can be used to create simple experiments, collect data, and analyze the eye tracking data. 


E-Prime is a program used for creating experiments. E-Prime can be used in combination with both Tobii and EyeLink eye trackers. 


MATLAB is a software environment for numerical computing. It can be used to build experiments and analyze data.


Python 3 is an open-source general-purpose programming language. 


OpenSesame is a free program to create experiments, similar to E-Prime.


Qualtrics is the online research survey tool of Leiden University. It offers different question types, branch logic, and the ability to expert to statistical software such as SPSSC. Researchers and students can use Qualtrics without any cost. Read more about Qualtrics on the University Library website.


Unity is a powerful cross-platform 3D engine and a user-friendly development environment to easily create 3D games. 


oTree is a framework based on Python that lets you build multiplayer strategy games, controlled behavioural experiments, surveys and quizzes.

Data analysis is the process of converting raw data into information that can be used to answer research questions. To help you interpret your raw data SOLO Research and Lab Support supports different types of data analysis software.

Staff members can install the software on their own computer through the Software Center or apply for the software at the ISSC. Students can make use of most of this software in the FSW Data Analysis Room 1B02.

Data analysis room

Room 1B02 is a small computer room with 5 computers. The computers are exclusively meant for using specialized data analysis software (not SPSS or R). These computers can be used by researchers and students. A computer needs to be reserved on our reservations website.

Installed software:

•    Biopac AcqKnowledge
•    BrainVision Analyzer
•    E-Prime & E-Prime Extensions for Tobii
•    Noldus the Observer
•    PhysioData Toolbox
•    Tobii Glasses Analyzer
•    Tobii Studio
•    VU-DAMS

Local ExperimentData folder

Because working from a network drive (e.g. J: or P:) can negatively impact the computer’s performance and working from an external hard disk is not advised due to privacy regulations, users can use the local ExperimentData folder. This folder is accessible via the Desktop shortcut or via C:\Users\[ulcn name]\ExperimentData.

When using the Experiment Data folder, be aware of the following:

  • The ExperimentData folder is a local folder on the computer. Data stored in this folder can only be accessed on that particular computer in 1B02.
  • No backup is being made. The data should be backed up to a network drive (e.g. J: or P:) at the end of the day.
  • The ExperimentData folder including all data will be automatically deleted when the user has not used the computer for a period of 30 days. 


LU card access is required when using 1B02. LU card access to 1B02 can be requested at the Service Desk. Access for students needs to be requested by their supervisor. For access, send the following information of the person that needs access to the Service Desk:
•    LCN name;
•    LU/umail address;
•    LU card number;
•    Start and end date of access;

Due to privacy regulations, the door must be locked when nobody is present. The LU card needs to be used to lock and unlock the door; the door does not automatically lock when closed.

SONA is the participant management tool used by research facilities. The system provides an easy way for researchers to create and manage their studies, recruit human subjects and schedule timeslots.

Participants can sign up for a study by viewing a list of studies and available timeslots. A researcher account allows you to create and manage studies. You can apply for a researcher account by sending your information to proefpersonen@fsw.leidenuniv.nl.


All first-year students of the bachelors Psychology and Pedagogical Sciences are obliged to participate in scientific research for their first-year course Academic Skills Tutorial. Therefore, each student has to obtain 16 participation credits which will be granted through SONA. In general, one credit corresponds with spending half an hour as a participant in scientific research organized by members of the Faculty of Social and Behavioural Sciences. When students have obtained all 16 credits, they can still participate in the experiments but will instead receive monetary compensation.

Students will also make use of the SONA system in order to carry out the research for their bachelor/master thesis. To do so, students have to request a researcher account which allows them to set up and manage a study. By using a researcher account credits can be granted to the participants.


SONA is used by researchers as a recruiting and management tool for their current studies. For all students and PhD candidates Researcher accounts will suffice. For other academic staff such as professors, a Principal Investigator account will be created by the administrators.

External participants

SONA is also used by external participants, i.e., students who are not enrolled in a programme organised by Psychology/Education and Child Studies or simply participants who are not affiliated to Leiden University. External participants can create an account themselves on the SONA website. These participants receive monetary rewards, but make use of SONA because of the time slot management and recruitment purposes. Granting monetary rewards takes place outside of SONA.

FSW researchers can use the High-performance cluster SLURM (successor of the old Shark cluster) at the LUMC for processing of large amounts of data. 

More information about how to connect, available software and getting a user account.

It is mandatory to sign up for a practical Linux and a SLURM introduction course in order to get started.

From autumn 2020 on, analyses will gradually move to the university-wide ALICE cluster (when the configuration of this cluster is ready).


All questions related to the SLURM cluster:
•    LUMC Linux team (ITenDI_Infra-Linux@lumc.nl)

For software-specific questions, please consult:
•    The colleagues at your own research group 
•    Henk van Steenbergen (SLURM key user at FSW)
•    Kerwin Olfers at SOLO
