How to write a function that reads a log file and outputs structures with the relevant data?

I want to create a function which will prompt the user to select a LogFile.txt file using uigetfile. (I have attached the file I want to read)

In the file the ‘important’ fields are: Event Type (that describes whether there was a scanner pulse, a picture presentation or a button press), code (which describes the type of event) and time, (time of the event, in tenths of milliseconds). The function should output a structure LogTimes with the following fields:

1. PD2: Time (in milliseconds!) of the picture indicating a press with the second finger( ‘Picture D2 ’).

2. D2: Time (in milliseconds) of the button press with the second finger. 1

3. PD4: Time (in milliseconds) of the picture indicating a press with the fourth finger( ‘Picture D4 ’).

4. D4: Time (in milliseconds) of the button press with the fourth finger.

I have no idea how to approach this, any help would be appreciated!!

You can use Import File to generate a function that will import the data consistently for you, and generate the structure from there.
