  • Have you restarted OpenSesame after the installation? The plugins should be available from the item toolbar afterwards - potentially you need to click on the arrows at the bottom of the item toolbar to display additional items including the mousetra…
  • Hi, you do not need to upgrade pip. You are experiencing a common issue (on Windows) which we have described in the installation instructions: If the installation fails due to missing write access, you may have to run OpenSesame with administrator p…
  • Hi, we provide the installation instructions for the mousetrap plugin on the following page: https://github.com/PascalKieslich/mousetrap-os#installation Does this help? If it does not work: which version of OpenSesame are you using? And on which ope…
  • Hi, this means that you have e.g. 2 trials with only 3 recorded coordinates, 8 trials with only 4 recorded coordinates, 2 trials with only 5 recorded coordinates and so on. I think that so few recorded positions are rather unlikely to occur and migh…
  • Hi, that's interesting. Do you have an idea whether it is in principle possible in your study that start and end points are identical? Usually I would not expect this - except if participants can somehow not give a response in a trial (e.g., if ther…
  • Hi Leonie, I have to say that I am not 100 % sure that I understand your raw data format (from the name of your dataset I would infer you are using Gorilla, but I don't know how the data format of Gorilla looks like). Based on the import function f…
  • Hi Leonie, I think this warning message is the cause of the problem: "Warnmeldung: In mt_import_long(gorilla.traj, xpos_label = "x", ypos_label = "y", : After removing trajectory data, more than one unique row per mt_id rema…
  • Hi Leonie, this points to a problem during the preprocessing. Could you share your code, starting with the import of the trajectories until you run mt_measures? In addition, could you share any warning messages you receive? I would speculate that yo…
  • Hi Leonie, that code looks fine to me. The message above seems to suggest that some trials can only be found in gorilla_mt$data but not in gorilla_mt$measures. Could you maybe, in a first step, check that the number of rows is them same: nrow(gorill…
  • Hi, could post the code you used for aggregation? This would help me identifying the underlying problem. If you want to aggregate the MAD values, trajectories of different length should not be a problem per se. Best, Pascal
  • Hi Mike, all changes in the mousetrap package are documented here: http://pascalkieslich.github.io/mousetrap/news/index.html There have been changes in mt_measures, but none of them were related to the curvature indices (as far as I remember). There…
  • Hi Marios, I think the problem is that the mousetrap plugin only supports rect elements. If you inserted the buttons as pictures, you would have to draw an additional rect element around them and label this element to get the click in the respective…
  • Hi, you can name elements on the sketchpad by selecting the corresponding element and then entering a value in the name field that is displayed in the row above the sketchpad preview (the default value is auto, i.e., unspecified I think). Once you'v…
  • Hi there, if I understand you correctly, you would like to create a plot that displays the mouse trajectory of the participant? If this is the case, my next question would be: when do you want to create and display the plot? Within the study? Or aft…
  • Hi there, you are correct, you can use the add_labels argument. The code should look something like this: mt_data <- mt_import_long( raw_data,xpos_label="X",ypos_label="Y",timestamps_label="Time", mt_id_label=&qu…
  • Hi Mike, regarding 2): you are correct in that this can only happen towards the end of the trial, i.e., if the response is given before the time interval that is depicted in the figure. So this explanation is probably not relevant if we look at earl…
  • Regarding the second question ("In our stop-signal task, the stop signal sounded after a delay that was set using a staircase procedure in each trial. Suppose we want to calculate distance that an individual went in each stop trial after hearin…
  • Hi Anton, regarding your first question ("What I have in mind is first 25% of trajectory. Is it possible to compute maximum AND averafe acceleration on this part?"): I think there are two ways how you could to do this (not sure which way …
  • Hi, I just realized that I forgot to answer the two questions you posted a while ago, sorry for that! What is the current status concerning your questions? Are they still up to date? Best, Pascal
  • Hi Mike, that's a good question. I think that there could be different reasons for this apparent discrepancy: 1) I just wanted to point out that the heading on your first graph says LONG DUR and the heading on your second graph says SHORT DUR so I j…
  • Hi, maybe one note in advance: I think that you reported this or a similar issue also on GitHub: https://github.com/PascalKieslich/mousetrap-os/issues/7 Is it the same are a related issue? If so, I would prefer to discuss it here in the forum. As a …
  • Hi Timo, I think that I do not completely understand the procedure you want to implement, but maybe some general comments that might help: The response time is recorded by the mousetrap_response item in the variable response_time_[item_name] so shou…
  • Hi, which OpenSesame version are you using (+ on which operating system)? Do you have the most recent development version of mousetrap-os installed (see https://github.com/PascalKieslich/mousetrap-os#installation)? Best, Pascal
  • Hi David, concerning the first question: Is this something that needs to be implemented in the experiment itself? That is, except for the fact that you want to start tracking coordinates only when y=128 are crossed, is there something that happens a…
  • Hi there, I think the comment by @cesco is correct. The problem is that OpenSesame for Mac OS and for Windows seem to be using different versions of the pip library. We already discussed this issue in the following thread: https://forum.cogsci.nl/di…
  • Have you followed the instructions at https://github.com/PascalKieslich/mousetrap-os/blob/master/README.md#installation? If you are using Windows you need to run opensesame as an administrator to avoid the access denied issue. Hope this helps! Best …
  • Hi there, the following is only a notification but not an error message: "You are using pip version 9.0.1, however version 19.2.3 is available. You should consider upgrading via the 'python -m pip install --upgrade pip' command." So in pri…
  • Hi, could you specify which version of OpenSesame you are using? If you are using a version of 3.2.0 or later: have you installed the most recent development version of mousetrap, as described here: https://github.com/PascalKieslich/mousetrap-os#dev…
  • Hi, glad to hear that you like the mousetrap software packages! :) How would you specifically like to define "acceleration on the first recorded section of the trajectory"? That is, what is the first recorded section? The first XXX ms? O…
  • Hi Mike, mt_measures computes four velocity related measures: vel_max: Maximum velocity (i.e. if there are both positive and negative velocities, the largest positive value) vel_max_time: Time at which maximum velocity occurred first vel_min: Minimu…
