Hi, I'm searching for an automatic script to insert commands G4 and M42 in a sequence of G1: I'm developing a matlab script image acquisition and I have a sequence of G1 commands that represent various positions (x,y,z) of the extruder of a 3d printer. M42 guarantees photo capture and G4 the pauses. I have to have one image for each position. in the code below there is an example of two image acquistions. So, i want to
obtain a matlab script to modify a sequence of G1 by inserting G4 P1500; M42; G4 P250; M42 between each one

That looks like the desired result? Can you show us what the unmodified input would look like?

in_filename = 'InputGcodeFileNameGoesHere.txt';
out_filename = 'OutputGcodeFileNameGoesHere.txt';
L = readlines(filename);
L = regexprep(L, '^G1.*$', '$1\nG4 P1500 ;ms, stabilization pause\nM42 P47 S255 ;photo capture, set 1 on pin 47\nG4 P250 ;ms, photo caption pause\nM42 P47 S0 ;set 0 on pin 47');
writelines(L, out_filename);
Though if you happen to be using MacOS or Linux, I would suggest just coding the as a shell script that invokes sed https://linux.die.net/man/1/sed
