Sorting arrays

Hi all,
I have a series of file names in an array that I'm trying to sort with imagej macro language.

expt1-c1-f

expt1-c1-t

expt1-c1-v

expt1-c2-f

expt1-c2-t

expt1-c2-v

I'd like to sort the array like this

expt1-c1-t

expt1-c1-v

expt1-c1-f

expt1-c2-t

expt1-c2-v

expt1-c2-f

Further, I'd prefer to be able to specify the order of the sort : e.g. specify [t, v, f] or [f, t, v] or [v, f, t], etc.

Re: Sorting arrays

Hi Alex,

You can use control loops and "endsWith" as shown below:

Array1 = newArray("expt-c1-f", "expt-c1-t", "expt-c1-v", "expt-c2-f", "expt-c2-t", "expt-c2-v");
order = newArray("-t","-v", "-f");
Array2 = newArray(6);
counter = 0;
for(index=1; index<3; index++){
for(e=0; e<order.length; e++){
target = d2s(index,0)+order[e];
for(a=0; a<Array1.length; a++){
if(endsWith(Array1[a], target)){
Array2[counter] = Array1[a];
counter +=1;
}
}
}
}
Array.print(Array2);

Best Regards,
John

Hi Alex,

If you use a full-fledged scripting language [1] then you can lean on a
sort function and define your own comparator.

E.g., here is a Groovy script which does what you want:

data = [
"expt1-c1-f",
"expt1-c2-f",
"expt1-c1-t",
"expt1-c2-t",
"expt1-c1-v",
"expt1-c2-v"
]
println("before: " + data)
def order(s) {
return "tvf".indexOf(s[-1])
}
data.sort{a,b ->
if (a[0..a.length()-2] == b[0..b.length()-2])
return order(a) <=> order(b)
else
return a <=> b
}
println(" after: " + data)

Regards,
Curtis

Hi Alex,

You can add one more “for” loop into the macro and declare the number of “expt” & “c” as shown below.

Array1 = newArray("expt1-c1-f", "expt1-c1-t", "expt1-c1-v", "expt1-c2-f", "expt1-c2-t", "expt1-c2-v","expt2-c1-f", "expt2-c1-t", "expt2-c1-v", "expt2-c2-f", "expt2-c2-t", "expt2-c2-v");
numExpt = 2; //Number of experiment
numC= 3; //Number of c
order = newArray("-t","-v", "-f");
size = Array1.length;
Array2 = newArray(size);
counter = 0;
for(expt=1; expt<=numExpt; expt++){
for(c=1; c<=numC; c++){
for(e=0; e<order.length; e++){
target = "expt"+d2s(expt,0)+"-c"+d2s(c,0)+order[e];
for(a=0; a<Array1.length; a++){
if(endsWith(Array1[a], target)){
Array2[counter] = Array1[a];
counter +=1;
}
}
}
}
}
Array.print(Array2);

Regards,
John

Just to be clearer ...

Array1 = newArray("expt1-c1-f", "expt1-c1-t", "expt1-c1-v", "expt1-c2-f", "expt1-c2-t", "expt1-c2-v","expt2-c1-f", "expt2-c1-t", "expt2-c1-v", "expt2-c2-f", "expt2-c2-t", "expt2-c2-v");
order = newArray("-t","-v", "-f");
Array2 = newArray(12);
counter = 0;
for(index=1; index<3; index++){
for(e=0; e<order.length; e++){
target = d2s(index,0)+order[e];
for(a=0; a<Array1.length; a++){
if(endsWith(Array1[a], target)){
Array2[counter] = Array1[a];
counter +=1;
}
}
}
}
Array.print(Array2);

yeilds

expt1-c1-t, expt2-c1-t, expt1-c1-v, expt2-c1-v, expt1-c1-f, expt2-c1-f, expt1-c2-t, expt2-c2-t, expt1-c2-v, expt2-c2-v, expt1-c2-f, expt2-c2-f

I'd like to return

expt1-c1-t, expt1-c1-v, expt1-c1-f, expt1-c2-t, expt1-c2-v, expt1-c2-f, expt2-c1-t, expt2-c1-v, expt2-c1-f, expt2-c2-t, expt2-c2-v, expt2-c2-f

Thanks
Alex

John,

This works great, but it does fail when I have more than one experiment ... for example ...

expt1-c1-t
expt1-c1-v
expt1-c1-f
expt1-c2-t
expt1-c2-v
expt1-c2-f
expt2-c1-t
expt2-c1-v
expt2-c1-f
expt2-c2-t
expt2-c2-v
expt2-c2-f

gets sorted as :

expt1-c1-t
expt2-c1-t
expt1-c1-v
expt2-c1-v
expt1-c1-f
expt2-c1-f
expt1-c2-t
expt2-c2-t
expt1-c2-v
expt2-c2-v
expt1-c2-f
expt2-c2-f

Any thoughts?

expt1-c1-f

expt1-c1-t

expt1-c1-v

expt1-c2-f

Further, I'd prefer to be able to specify the order of the sort : e.g. specify [t, v, f] or [f, t, v] or [v, f, t], etc.
