Hi there, before answering your question, I would like to point out that I am not familiar with the Gorilla data format so I can probably only give you more general advice on how to format your data in a way that they are processed by mouestrap corr…
-
Hi Ester, thanks for providing a summary of the data. I would agree in that the structure seems to have the correct format required by mt_import_long . However, based on the information on the data you provide, I think that there is an issue with th…
-
Hi there, would it be possible for you to share a few exemplary rows of the dataset (mouse_dataincorrect) that you use as input for the mt_import_long function? This could make it easier to understand what might be the cause of the problem here. Bas…

Hi Valerio, it is possible to combine the mousetrap and the psynteract plugin for OpenSesame (we have done that a few times ourselves in the past 🙂). However, both plugins are only available for lab experiments and not available in OSWeb. Best, Pasc…

Hi all, 1) Regarding the installation of the mousetrap plugin for OpenSesame 3.3.0 or later (@eduard): When using OpenSesame 3.3.0 or later, you need to install the development version of the mousetrap plugin (as described here: https://github.com/P…

Hi there, if you only want to exclude the probelamtic trials, one "quick and dirty" solution could be to just exclude the ids that were reported directly after mt_import_mousetrap with mt_subset: m100msstop <- mt_subset(m100msstop, !m…
-
Hi there, I have a questions to better understand the issue. In your code and output it says after running mt_import_mousetrap: There were 22 warnings (use warnings() to see them) Have you inspected these warning messages and could post them here? T…
-
Hi there, this is an issue that was resolved in the current development version of the mousetrap plugin for OpenSesame. When using OpenSesame 3.3.0 or later (as in your case), you should install the development version of the mousetrap plugin (as de…
-
Hi So So, I think that calculating the distance depends on how you decide to implement the manipulation of the location of the target stimulus and response stimulus. Once you have decided on this, you can simply subtract the y positions (in case you…
-
Hi Felix, a number of example experiments including one that demonstrates how to use the shuffle horizontal operation in combination with the mousetrap plugin can be found here: https://github.com/PascalKieslich/mousetrap-os/tree/master/examples In …
-
Hi there, I have the following ideas regarding the issues you mentioned above: 1) Flipping trajectories In your preprocessing code, I did not see a step where you flip trajectories that ended on the right option to the left. If you do not do this, t…
-
Hi Mike, glad to hear the issue could be resolved. One thing I just wanted to mention (because it looked to me like you were reading in the processed MouseTracker files): in the mousetrap R package, we also provide the read_mt function (http://pasca…
-
Thanks for moving the discussion! @afkeve already opened another discussion in the mousetrap category which I answered here: https://forum.cogsci.nl/discussion/6440/mousetrap-osweb-support#latest Best, Pascal
-
At the moment, there are no plans for developing the mousetrap plugin for OSWeb, as this would require a complete in rewrite in JavaScript. See https://forum.cogsci.nl/discussion/5987/mousetrap-mouse-trajectory-tracking-in-web#latest for a related d…
-
Regarding @P_Barr's question: I think that there are still some problematic trials in your dataset that need to be excluded. Specifically, there is the above warning that you quote: In addition: Warning message: In mt_align_start_end(mt_data, use = …
-
Regarding @a.g.leontiev's question: I am not completely sure what you mean with "I meant not in the first part of a trial, but let's say first 100 of ALL trials". Do you mean you would only like to select a subset of trials for your analys…
-
Great to hear things are running smoothly now! Currently, there is no option in mousetrap that can calculate measures for only parts of the trial. However, depending on what measure you are interested in, functions like mt_deviations and mt_derivati…
-
Hi there, I think the problem might be caused by the fact that some of your trajectories do not contain unique time stamp values (i.e., there are trials where a specific timestamp value occurs multiple times). Depending on the import function that y…
-
Hi there, I also would speculate that the problem is due to missing values (NAs), probably missing values that are already occurring in the raw dataset (df_sst). Usually, mt_import_mousetrap should to a good job at checking for missing values and th…
-
Hi, good to hear that your import errors got resolved! Regarding the other issues: could you post the link to the discussion you are referring to? Best, Pascal
-
Hi there, when you say that you compared 3 cases, are you referring to 3 different conditions with mutliple observations each? If so, how many observations do you have in each condition? Which statistical test did you use to compare them? Usually, M…
-
Hi Marta, I am also happy to look into the installation errors of the mousetrap plugin if you want to share them here (+ it would be great if you could specify your operating system and OpenSesame version when doing so). However, the mousetrap plugi…
-
Hi Marta, as you correctly pointed out, mousetrap is unfortunately not available when running online experiments in OpenSesame via OSWeb, so you would have to find a JavaScript based solution for this I think. I moved your question to the OSWeb cate…
-
Hi Marie, thanks, Eduard, for moving this to the mousetrap category. @Marie: it would be great if you could provide us, as Eduard wrote, with your operating system and OpenSesame version number. Depending on both, we provide different installation i…
-
Hi, unfortunately, you can only specify up to 4 buttons when using the mousetrap_response item. However, if you use the underlying Python class called MT_response in an inline script, you can also specify more than 4 buttons. More information about …
-
Hi, I think that the reason for this warning message is that there are additional columns in your dataset that vary within the trial (aside from x, y and time_stamp). So, for example, assuming that you have additional columns called "vel" …
-
Regarding the third point: I just saw your post in the other thread here: http://forum.cogsci.nl/index.php?p=/discussion/5744/mt-aggregate Given that there are warnings already at data import, I think that these are the cause of some of the errors a…
-
Hi, I think that there are several questions and issues to discuss here - and I am not sure if I can provide the answer to all of them without knowing the details of the technical implementation of the tracking in the study and the raw data, but I …
-
That's an interesting question. I can only provide the information how mousetrap computes the initation time in mt_measures. It is exactly done as you describe, i.e., the initiation time is defined as the last timestamp before movement initializatio…

Hi, I just wanted to let you know that we have updated the development version of the mousetrap plugin which now should be usable under OpenSesame 3.3. You can find the instructions on how to install the development version of mousetrap in OpenSesam…
