Sorry I left out that before trying to remove the parentheses, there is the following code:


i = 27;
newTitle = getMetadata("Label");
print("\nOriginal:  " + newTitle);
newTitle = newTitle.replace("c:3/3 - ", "");
newTitle = newTitle.replace(".nd2", "");
newTitle = newTitle.replace("series 1", "");

Subject: s.replace question

[EXTERNAL]

I have been trying to remove parentheses from a string using the s.replace command and have been getting strange results.  (Practically, I was able to solve the problem by cutting the string apart, trimming out the parentheses and reassembling the string, but am asking specifically about the s.replace behavior.)


Code such as this

newTitle = newTitle.replace("(", "");

returns an error message.


Therefore, I tried setting a variable to "()" and used the following syntax:

print("Before trying to replace parentheses:  " + newTitle);
parentheses = fromCharCode(40, 41);
print(parentheses);
newTitle = newTitle.replace(parentheses, "");
newTitle = newTitle + IJ.pad(i, 3);
print("Processed:  " + newTitle);
with output that does not remove the parentheses:

Original:  c:3/3 - KO_1 nM_rep2_007.nd2 (series 1)
Before trying to replace parentheses:  KO_1 nM_rep2_007 ()
()
Processed:  KO_1 nM_rep2_007 ()027

And odder, the output in this case inserts "xx" between every character:


print("Before trying to replace parentheses:  " + newTitle);
parentheses = fromCharCode(40, 41);
print(parentheses);
newTitle = newTitle.replace(parentheses, "xx");
newTitle = newTitle + IJ.pad(i, 3);
print("Processed:  " + newTitle);



Original:  c:3/3 - KO_1 nM_rep2_007.nd2 (series 1)
Before trying to replace parentheses:  KO_1 nM_rep2_007 ()
()
Processed:  xxKxxOxx_xx1xx xxnxxMxx_xxrxxexxpxx2xx_xx0xx0xx7xx xx(xx)xx027



Any ideas?


Thank you!
