In your text file there is only X & Y position data and no Z… what should happen?

edit: sorry, you said you were after 2D tracking data.

What is the relevance of the similarity parameter for each frame?

ignoring the similarity parameter, this seems to work, but I will need you to upload an actual file with more than one object to test.

Also keep in mind there is no error handling, this is just a quick flimsy solution.

fn importPFTrack2D fName =
(
	local allLines = for l in ((dotNetClass "System.IO.File").readAllLines fName) where l[1]!="#" and l.count>0 collect l
	local pos = 1
	while pos < allLines.count do
	(
		with animate on
		(
			local obj = point name:(substituteString allLines[pos] "\"" "")
			pos+=2
			local frames = allLines[pos] as integer
			pos+=1
			for i = 1 to frames do
			(				
				local vals = filterString allLines[pos] " "
				at time (vals[1] as integer) obj.pos = [vals[2] as float, vals[3] as float, 0]				
				pos+=1
			)
		)		
	)	
)

Wow thanks man , I didn’t except to get a reply so soon!
As soon as I get to th office I’ll upload the file.
That is super helpful , thanks alot !

thanks again rotem , i really appreciate your help .
i have uploaded the file to here
thanks!!

You’re quite the early bird…

fn importPFTrack2D fName =
(
	local allLines = for l in ((dotNetClass "System.IO.File").readAllLines fName) where l[1]!="#" and l.count>0 collect l
	local pos = 1
	local quot = "\""
	local space = " "
	while pos < allLines.count do
	(
		with animate on
		(
			local obj = point name:(substituteString allLines[pos] quot "")
			pos+=2
			local frames = allLines[pos] as integer
			pos+=1			
			for i = 1 to frames do
			(				
				local vals = filterString allLines[pos] space
				at time (vals[1] as integer) obj.pos = [vals[2] as float, vals[3] as float, 0]				
				pos+=1
			)
		)		
	)	
)

usage:

importPFTrack2D @"C:	est.txt"

The function seems to work fine for me, have you tried it?

yea it works !!
tank you so much!!

sure, glad to help
