Hi Jelka, Please excuse us for this late reply ! Since the end of last year we moved to GitHub (https://github.com/bachlab/PsPM), so if you could open a new Issue there it would be amazing ! About your issue: unfortunatelly it is very difficult to say you what is the error you are making without having the raw data :/ But as you described it, it seems that your error is in the import structure that you are using. To be entirely sure may I ask you while opening the new issue on GitHub to upload a...
-
Number of marker names and number of marker onsets mismatch
-
pspm_get_events misses markers that correspond to the first sample row
-
Fixed on github (see https://github.com/bachlab/PsPM/issues/15). I close the ticket.

Dear Sasa, What you have to remember is that PsPM will always return you the pupil size in units of diameter. Here is how the import and conversion are done : At first, pspm_get_eyelink receives your data either in 'diameter' or 'area' (depending on how you have recorded them) but these data are still in 'au' and scalled. Then this function determines to which case your data belong ('diameter' or 'area') and transfers them to another function (lines 321, 328) called pspm_convert_au2unit with the...

Dear Sasa, Indeed the SR Research team is using a scaling factor between area and diameter of the pupil in order to have the right scaling during their conversion process. In PsPM on the other hand we scale that values in pspm_get_eyelink funtion, then when we use area2diameter we only worry about the standard conversion formula (A=pi*r^2). Regards, Ivan

Dear Sara, I'm glad to hear that the solution worked for you. For your other questions, I have to apologize. In my answer for the previous topic, I've forgotten to specify that you have to apply a high-pass filter to your data otherwise the model would not fit correctly. Please excuse me for that omission. Here are the steps if you use PsPM Batch Editor: To apply a high-pass filter, in the module "GLM for SEBR", you have to select Filter Settings, enable it and then select High-Pass Filter, you choose...

Dear Anna, Thank you very much for the details you have sent us and I am sorry for the delay I have taken to respond you. Here is my answer: I have achieved to reproduce entirely your error message except for the first line which is Warning: Escaped character '\M' is not valid. See 'doc sprintf' for supported special characters. Let us know if it persists after the following advice. Apparently you are using arbitrary units for diameters of the pupil and these arbitrary units do not correspond to...

Dear Anna, We managed to partially reproduce your error. Can you nevertheless send us more lines of your error message please ? It would help us to fully understand the problem and provide you a good support. Kind regards, Ivan. P.S: You can even copy/paste the whole error and use paragraph to highlight it.

Dear Anna, Thank you for relating this issue. What you are doing is correct - but the output files shouldn't get so big. We looked at it and the problem comes from your input data. Indeed, you input two arrays of size 1403368x1 without filtering it so during exetution PsPM will create five arrays of same size and three matrices of size 1403368x65. This is a huge file that MatLab tries to save. In theory it could do it but for that we have to modify our code. We will maybe implement that in a later...
