Re: [micro-manager-general] Timestamp in MM stacks

[Cammer, M. <Mic...@me...>]

I sent a reply to this but haven't seen it posted, so I'll write again-- apologies if it is a repeat.

Each image has a lot of metadata stored in it such as devices, filters, etc.  This includes time.  Here is a macro I wrote over the weekend for our use to get the times out.  Later we will modify this to reassign the metadata for saving in ImageJ.  If you put tabs in ("/t"), then Excel will parse into separate columns.

The protocol is in ImageJ:
import the images to a stack  
run this macro

//=================================================================================
macro "get times from Olympus MM1.4 images" {
  requires('1.45j');
  print("");
  print(getTitle);
  for (slice=1; slice <= nSlices(); slice++) {
    setSlice(slice);
    a = getImageInfo();
    b = split(a);
    for(i=0; i<b.length; i++){
      if (startsWith(b[i], '"ElapsedTime-ms"')) {
        b[i+1] = replace(b[i+1], ",", "");
        if (slice>1)
          print(getSliceNumber(), b[i], parseInt(b[i+1])/1000, "sec", (parseInt(b[i+1])-previoustime)/1000, "sec");
        else
          print(getSliceNumber(), b[i], parseInt(b[i+1])/1000, "sec");
        previoustime = parseInt(b[i+1]);
      } // if
    } // for i
  } // for slice
  selectWindow("Log");
}  // macro get times
