Hi Vishal,[quote:355e98e378]imstat xyz.fits | scan (datapars.sigma,datapars.datamin,datapars.datamax) [/quote:355e98e378]Shouldn't you instead be running imstat with the following flags, to define the correct output format?[code:1:355e98e378]imstat xyz.fits format- fields="stddev,min,max" | scan (...) [/code:1:355e98e378]This should make imstat output the 3 numbers you want and nothing else, so your scan should work. Right now (if you are literally doing what you said above) you are scanning the comment line that imstat outputs by default to explain what the columns are.Cheers,James.
