batch importing files - double backslashes?

Hello,

I have run into a problem which might be quite trivial.

I am trying to batch process a folder, for which I used the 'Process  
Folder' template macro code (I have copy pasted it at the bottom of  
this message).
The first command is to import the file with Bioformats Importer,  
however I get an error:  ")" expected  .

The command is:
run("Bio-Formats Importer", "open=["input + file"] autoscale  
color_mode=Default display_metadata view=Hyperstack stack_order=XYCZT");

Where input is the path from getDirectory, and file is the filename.
I assume I am making a basic mistake here somewhere.

I thought the problem might be due to a case of single or double  
backslashes, as when you ' print(input + file) ', in the log there are  
only single backslashes visible in the path name (but perhaps  
internally the string does contain 2 backslashes?)



I looked at some suggestions online and tried replacing the input  
string as follows:

inputReal = replace(input,"\\" , "\\\\")
This gave the error:  //java.util.regex.PatternSyntaxException:  
Unexpected internal error
near index 1

or

inputReal = replace(input,"\\" , "/")
This gave the error: ' ";" expected '  , when trying to ' print(inputReal); '


Any suggestions?

Thanks

'Process Folder' template macro code :

input = getDirectory("Input directory");
output = getDirectory("Output directory");

Dialog.create("File type");
Dialog.addString("File suffix: ", ".lsm", 5);
Dialog.show();
suffix = Dialog.getString();

processFolder(input);

function processFolder(input) {
        list = getFileList(input);
        for (i = 0; i < list.length; i++) {
                if(endsWith(list[i], "/"))
                        processFolder("" + input + list[i]);
                if(endsWith(list[i], suffix))
                        processFile(input, output, list[i]);
        }
}

function processFile(input, output, file) {
        // do the processing here by replacing
        // the following two lines by your own code
        print("Processing: " + input + file);
        print("Saving to: " + output);
        print(output);
