Convert intiger into ascii character in a .qual file

[zillur]

Hi there,
I have a quality file like this:

>M00365:7:000000000-A48JK:1:1101:14885:1320
32 32 32 32 32 37 37 31 33 33 33 33 38 38 38 38 34 36 32 37 36 37 36 36 36 36 38 35 37 38 38 39 38 38 36 30 32 32 37 39 37 36 36 34 36 38 38 34 36 36 37 37 37 39 36 36 38 36 30 38
>M00365:7:000000000-A48JK:1:1101:16088:1320
33 33 32 32 33 37 37 37 37 37 37 37 38 38 38 17 36 36 37 37 38 38 38 38 38 38 38 39 33 34 38 38 36 36 36 36 36 38 39 39 39 37 37 38 37 38 38 39 37 38 34 36 30 36 36 36 38 38 35

truncated for convenience. I want to convert them into:

>M00365:7:000000000-A48JK:1:1101:14885:1320
HIKALUIKJHKHKHUIKJHHIJHGFUIYDFHKKIJGHJKIIIII...............and so on.....
>M00365:7:000000000-A48JK:1:1101:16088:1320
IKJHGFRFIKJGDHKBFRTJJKH........and so on.......

Any suggestion? I also want them sort according to header.

Thanks in advance for your comments.

use awk:

   awk '/^>/ {print;next;} {for(i=0;i<NF;++i) printf("%c",33+int($i));printf("\n");}'

I don't know your endoding. I just put +33. However, your example is strange, if a quality starts with

32 32 32 32 32  ....

then the translated qualities should be the same isn't it ?

Thank you very much. That exactly what I wanted.
