In ENVI, I'm trying to use some statistics gathered from a Region of Interest. I
extracted them and saved them to a file, pan15.sta. I then tried using the
following code (almost the same as the example in the programmer's guide) to get
the stats out of the file:
envi_get_statistics, '/export/home2/jmcfee/casi/itres/dres9707/work/pan15.sta',$
mean=mean,dmax=dmax, dmin=dmin, pos=pos
if (pos(0) eq -1) then return
for i=0, n_elements(pos)-1 do $
print, 'Band', pos(i), dmin(i), dmax(i), mean(i)
end
I get an error at the "envi_get_statistics" line:
% Array requires more memory than IDL can address.
% Execution halted at: STATS_READ
% ENVI_GET_STATISTICS
% $MAIN$ 1 /home/jmcfee/idl_lib/statsprog.pro
[my program file]
The file exist there and I've checked it out for format, etc. I have no other
files open and over 2.5 Gigabytes of disk free and oodles of free RAM. Is anyone
aware of a bug like this in envi_get_statistics?

I got an error like that last week in IDL. When I checked into
it I found I was asking for something like 8 million Gigabytes.
I told our system guys I needed more memory.
