Arrays and string wildcards
Locked
 
|
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 -- ImageJ mailing list: http://imagej.nih.gov/ij/list.html |

Hi Alex,
I think the following macro command will do this: Array.deleteValue(array, value); ...where value = ".jpg" Greg. __________________________________________ Gregory James Clinical Scientist (Nuclear Medicine) Department of Physics and Nuclear Medicine City Hospital Dudley Road Birmingham B18 7QH 0121 507 4043 ________________________________ From: Aleksandr Mironov <[hidden email]> Sent: 19 January 2021 15:04 To: [hidden email] <[hidden email]> 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.

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.

Dear Aleksandr,
The following code should make the deal: dirInput = getDirectory("Choose Input Directory "); list = getFileList(dirInput); for (i = list.length - 1; i >= 0; i--) if(endsWith(list[i], ".jpg")) list = Array.deleteIndex(list, i); // list = Array.deleteValue(list, list[i]); Array.show(list); I have left both the Array.deleteIndex and Array.deleteValue options for you to choose your preferred one.

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.
