Dear Users,
Below are the few lines of the text (Raw.txt) which should have three columns of data.
  • Column 1: index (e.g.20121128,)
  • Column 2: clock_tick (e.g. 12:51:16.812:)
  • Column 3: comments (e.g. Click detected at (0, -2) from the center of target 45. Absolute position: (880, 553) out)
The problem is when I use textscan or importdata, with delimiter. The imported file assumes there is either 2 columns (col, col&3combined), or 3 to 5 columns (based on the position of the comma)
For example the following row would be passed as 5 columns
20121115, 15:00:31.796: Click detected at (0, 0) from the center of target 13. Absolute position: (880, 249) out of (1280, 918).
Raw.txt

You forgot to attach raw.txt, so we can't try anything, yet. After you read this and fix your formatting, and post your file, I'll check again.

Use a textscan format of '%f,%{HH:mm:ss.SSS:}D%[^\n]'
