Display File Names vs Time Stamp

Notebook name: display_file_names_vs_time_stamp.ipynb

Description

This notebook extracts the acquisition time and displays

  • time stamp vs file index
  • relative time stamp offset vs file index (offset between each file)
  • absolute time stamp offset vs file index (offset relative to first file loaded)

How to Use It?

Select your IPTS

Select Data Set

Select Images you want to check

Check the [file selection tool tutorial](/tutorial/notebooks/file_selector/#folder_navigation) to learn how to use the file selector tool.

Once you have selected your data, you will see a progress bar as the time stamp metadata are retrieved from the files.

Display Time Stamp

The next cell will plot on the left side the relative time offset in seconds, and on the right side, the absolute time offset in seconds.

Relative time offset (s)

This is the time between each image.

relative_time(i) = acquisition_time(image(i)) - acquisition_time(image(i-1))

Absolute time offset (s)

This is the time spent since we started to acquire the images. For the first image, this absolute time is 0 of course.

absolute_time(i) = acquisition_time(image(i)) - acquisition_time(image(0))

Here is the plot we got when using an acquisition time of 30ms

List Files Loaded

The next cell display a list of all the fulle, relative and absolute time stamps.
