question: macro for automatic image stack summing

[Sebastian Voigtländer]

Dear all,

I try to write a simple macro to help me with image analysis for my thesis.
It should:

1. open .tif image stacks from an input folder
2. execute run("Z Project...", "projection=[Sum Slices]")
3. save the files in an output folder


my macro (so far):

function sum_stacks(input, output, filename) {

    run("Bio-Formats Windowless Importer", "open=input + filename");
    run("Z Project...", "projection=[Sum Slices]");
    run("Save", "save=[output+filename]");
    run("Close");
};

input = "*specified input folder with stacks of .tif images*"
output = "*specified empty output folder*"

list = getFileList(input);

for (k = 0; k < list.length; k++) {
    sum_stacks(input, output, list[k]);
};



When I run it I get the error message:

Sorry, there was an I/O problem during import.


Since I have no idea what's wrong, I would be very grateful for any help!

Cheers,
Sebastian

Dear Sebastian,

The line    run("Bio-Formats Windowless Importer", "open=input + filename"); should read run("Bio-Formats Windowless Importer", "open="+input+filename); or in the case you have spaces in your directory or file names run("Bio-Formats Windowless Importer", "open=["+input+filename+"]");
Input and filename are variables. You don't want to open a file with the name "input + filename" but with the directory and name stored in input and filename.

However, I never get the error message with your code if I do not also change the input and output code to:

input = getDirectory("specified input folder with stacks of .tif images");
output = getDirectory("specified empty output folder");

Also your run("Save", "save=[output+filename]"); should read run("Save", "save=["output+filename+"]");

Best wishes

Kees

Hi Sebastian,
You can do it with the batch function :
Process/Batch/macro
without need to code.
