How to merge every n lines into one line?

I want to merge every 16 lines into one line, how can I do that? My file looks like below:
0

after merging, the first line of the new file should look like:
0,.,2,2,.,0,0,.,0,0,.,0,0,.,0,0

Could someone give me some suggestions? Thanks.

Code:
awk 'NR%16 {printf("%s", $0); next}
       {print $0} ' infile > newfile

One way using awk.

Smilie Thank you so much. It is able to print every 16 lines into one line without comma.

why I can't use cat/more/head to read the output file? It always has one column as my original file?
