changing filenames

[Devrim Pesen Okvur-2]

I would like to change tiff file names as follows:
1- place two zeros in the beginning so that the order is 001 002 ... 100 instead of 1 2 ...100
2- shorten the file name from 1_a_xxx_yyy to 1_a

Combining the two above,  filename of 1_a_xxx_yyy will be changed to 001_a

Any help is appreciated.

Devrim,

you need to keep the left part of the file name, extending to the second
underscore, then pad the numeric part that extends to the first underscore
to 3 chars, and finally combine the padded index with the remaining part.
This translates in the following macro function :

requires ('1.45d'); // for IJ.pad function
print (changeFileNames('1_a_xxx_yyy'));

function changeFileNames(s) {
  short = substring(s,0,indexOf(s,'_',indexOf(s,'_')+1));
  paddedIndex = IJ.pad(parseInt(substring(short,0,indexOf(short,'_'))),3);
  return ''+paddedIndex+substring(short,indexOf(short,'_'));
}
////

Sincerely,
Jerome.

 Jerome,

Shortening the file name works. Thank you. (I placed the relevant line
 with s to path into the loop in the macro I had)

If the filename is 1_1_xxx_yyy how can it be changed to 1_01_xxx_yyy?
(There are more than 10 files so the ordering works when they are
numbered 1_01..., 1_02..., etc.)

I appreciate your help.

Devrim,
here's another solution using the split function. You can specify padding
length for both the first and the second parts in your filename motives.

   requires ('1.45d'); // for IJ.pad function

print (changeFileNames2('1_2_xxx_yyy',3,3));


function changeFileNames2(s,length1,length2) {

  parts = split(s,'_');

  return
''+IJ.pad(parseInt(parts[0]),length1)+'_'+IJ.pad(parseInt(parts[1]),length2);

}

Sincerely,


Jerome
