It seems that Array.deleteValue will only delete an exact value, and not deal with substrings nor regular expressions.
You may want to instead use the recently added Array.filter function, which works with regular expressions.
This will extract those files you are interested in, instead of removing those not of interest.
See this example:
dir = getDir("imagej") + "samples/";
print("dir: " + dir);
list = getFileList(dir);
list2 = Array.deleteValue(list, "AuPbSn40.jpg"); //remove this file
list3 = Array.filter(list, ".gif"); //extract all gif files
list4 = Array.filter(list, "(\\d+)"); //extract all files containing numbers
Array.show("lists", list, list2, list3, list4);
It would be useful though if Array.deleteValue would work with regular expressions, when the argument is in parentheses.

Hi Greg,
I put it like that:
dirInput = getDirectory("Choose Input Directory "); list = getFileList(dirInput);
list2 = Array.deleteValue(list,".jpg");
Array.show(list);
Array.show(list2);
It does not work in that way both arrays are the same. "*.jpg" does not make a difference as well.
Regards,
Alex

Hi Alex,
I think the following macro command will do this:
Array.deleteValue(array, value);
...where value = ".jpg"

Subject: Arrays and string wildcards
Dear listers,
I am writing a macro with which I want to correct certain files in a directory and convert them to different formats. Some of files are not readable by ImageJ or Bioformats/Fiji and need to be excluded from opening. Others may need different operations depending on file type.
If I get the array of filenames from this directory can I delete array elements using not exact string but a wildcard (like "*.jpg")?
Or is there any other way to make conditions based on file type?
Thank you in advance!
Best regards,
Alex Mironov
