When I try to import idfreader, an error always shows up:

ModuleNotFoundError: No module named 'detectors'

This is because idfreader imports functions from the file detectors but cant find its location.

Currently I have copied the pygazeanalyser folder from github into my dist-packages folder for Python 3.
Is there a formal way to install it so that the path to all the files of pygazeanalyser is recognised?

Hi esdalmaijer,
Although I could only find the "slideshow" example here: http://www.pygaze.org/resources/examples/slideshow.zip

I thought this is probably the best place to report the following bug

constants.py
Line 14: LOGFILENAME = input("Participant name: ")

doesn't work on python 2.6 / 7 (at least, it doesn't do what you intend... simple explanation here: http://cis.poly.edu/cs1114/pyLecturettes/raw_input-input.html

Perhaps the easiest work around here is to replace that line with something like the following (untested!)...

import sys
if sys.version_info < (3, 0):
LOGFILENAME = raw_input("Participant name: ")
else:
LOGFILENAME = input("Participant name: ")

Cheers,
Ben.

Hello, there is some sample EDF files for analysis?

The code assumes that the recording starts with no blinks. I recommend adding 0 at the beginning of the 'miss' array to prevent miss identification of blinks.

Hello! I'm trying to produce a heatmap from an EyeTribe data file. The data seems to load and parse correctly, but gazeplotter.draw_heatmap keeps throwing TypeErrors.

import eyetribereader, gazeplotter, detectors
sub = eyetribereader.read_eyetribe("**********/subject-502.tsv", "start_trial", "stop_trial")
t = sub[15]
fixations = detectors.fixation_detection(t['x'], t['y'], t['time'])
gazeplotter.draw_heatmap(fixations[1], (1280, 1024))

In Python 2.7.13, this results in:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "gazeplotter.py", line 227, in draw_heatmap
    heatmap[y:y+gwh,x:x+gwh] += gaus * fix['dur'][i]
TypeError: slice indices must be integers or None or have an __index__ method

And in Python 3.6.0, it gives:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "************/PyGazeAnalyser/pygazeanalyser/gazeplotter.py", line 199, in draw_heatmap
    heatmap = numpy.zeros(heatmapsize, dtype=float)
TypeError: 'float' object cannot be interpreted as an integer

Can you tell what I'm doing wrong? I'm on Arch Linux, with matplotlib 2.0.0 and numpy 1.12.0.

Hello.
I'm not sure if the project is still alive (last update was 2 years ago). But...
I've tried to create some pictures with analyser and found that data with zero values isn't excluded. Because of that I have many fixations and hight "temperature" in the upper left corner. Is it a bug? There are no problems to remove missing values with the following code:

#remove empty values
mx = numpy.array(x==missing, dtype=int)
my = numpy.array(y==missing, dtype=int)
x = x[(mx+my) != 2]
y = y[(mx+my) != 2]
time = time[(mx+my) != 2]

I want to create heatmaps from existing data not collected with pygaze (rather collected via python and eyelink). I am stuck trying to figure out what the required .txt file is supposed to contain as one was not created when I collected the data. I ran the example (slideshow) and tried to reconstruct a .txt file from that example, but ran into this error when I ran the analyzer script with my data:

saccades = edfdata[trialnr]['events']['Esac'] # [starttime, endtime, duration, startx, starty, endx, endy] IndexError: list index out of range

Any help is appreciated.

I have data from Tobii Pro 2 Glasses. I have attached the CSV File. I want to plot fixations and heatmaps over the images. I have reader_tobii file. I don't have trials or events. I also want to know what is there in the .txt file as mentioned in the analysis.py code. I don't have any .txt file. Please help if possible.

Hi,

Using the EyeTribe scanner creates a tsv file in the slideshow folder. But the code for the pygazeanalyzer requests a edf file and thus says no data found.

Do I have to convert tsv to edf ?

It is the issue from ECEM workshop

Hi,

I have a file which contains readings from pytribe for more than 20 images. However, when I use the analyzer for doing the analysis, I get an error after the 12th one. The issue is with opening too many handles for the figures when its saving it.

It can easily be handled by splitting the files into two and doing the analysis but I just wanted to notify you regarding the error.

Thanks

Hello. when i use analysis.py in example it gives me no plots in output. I have demo.asc and demo.edf files. what is the problem?
i think it's because of the demo.txt file. what should be in that file? thank you.
