Hi Kefe.
Despite I do not understand the weird prefix naming, I would like to put
some intro into naming anyway.

You got this error, because no active image with this name is open. Herbies
code "hide" the suffix (e.g. .tif), which would be the problem. He has
split the title into the array "nme" consisting of element 0 = "filename"
and 1 = ".tif" (suffix). If you want to concatenate this with hard coded
prefix you have to do it like this:

imgName="c:1/2 - "+nme[0]+nme[1] //in case you want to include suffix

this is equivalent:
title=getTitle();
run("Split Channels"); //or whatever split function you use
selectWindow("C1-"+title); //or whatever suffix you need - just exchange
"C1-" with "your_preffix". This just should work.

Anyway, more "safe" would be collect resulting images names and use them
e.g. in array. Here is an example code:


//open("/home/schebique/Obrázky/A1/confocal-series.tif");
run("Confocal Series (2.2MB)");
nI_pre=nImages; //actual number of opened image windows

run("Split Channels"); //splitting channels resulting in
C1-confocal-series.tif etc.
nI_post=nImages; //number of images after splitting
newImagesCount=nI_post - nI_pre +1; //+1 because original was closed, but
we have one image more after split
img=newArray(newImagesCount); //new array where we will collect image titles
count=0; //counter for the array index
for (n=nI_pre; n<=nI_post; n++) { //loop through desired images
selectImage(n); //selecting image
img[count]=getTitle(); //getting title into the array
count++; //index counter increment
}

//loop for printing
for (a=0; a<img.length; a++) {
print(img[a]);
}
//direct selecti of new channel images
selectWindow(img[0]); //select C1
selectWindow(img[1]); //select C2
//example how to copy into the parameter:
C1=img[0]; //params could be more intuitive furthur in the code
C2=img[1];
//loop for close new windows only
for (a=0; a<img.length; a++) {
selectImage(img[a]);
close();
}

Just to be complete I usualy use a little different way to separate name
from .tif suffix:
title=getTitle();
name=replace(title, ".tif", "");
print(title+"\n"+name);

Hopefully you can find some inspiration.
Best Ondrej
