Heaven forbid that students encounter a steep learning curve.... :o\

I'm still confused tho' - your employer is using *Excel* to visualise/process images?? Is that
right?

Thanks Reimar,

My employer wants the data in Excel format for both storage and visualization
reasons. He and most of the students he employs here are already familiar with
Excel, and he wants the data to be available in Excel workbooks so they can
immediately start analyzing them without learning any new programs. It makes
things more difficult for me as the programmer, but the logic is that the learning
curve is not as steep for other students in the lab. I'd love to use an
IDL-supported format, but everyone likes their Excel.

I believe the only way is to write many ASCII files, but I am a bit
surprised
why you want to calculate the data by EXCEL if you are able to write Idl
functions.

If it is because of seeing the data in tabulars you can use

f=dist(400)
xvarshow,f
xvarshow,f,/edit (for editing)

If it is because of storing the data you should have a look at hdf or
netCDF.
If you are interested I can give you more examples.

I am on a Mac, but I'm more familiar with PCs. Currently I am just writing
text data files for each movie frame and importing them one by one into Excel.
I was hoping it would be possible to write a multi-sheet.xls file directly.
I'll look into Do_Apple_Script. Thanks.

I am fairly confident that this is not possible using IDL. There have been
a few posts regarding Excel and queries for routines to read/write .xls
files that have gone mostly unanswered. Since we have no idea how you are
writing data to Excel it is hard to say. If you are on a mac, you could
probably do it with "DO_APPLE_SCRIPT" but I have only used ActiveX/VBA on
the PC so that's a guess.

I really think that it would be far easier and faster to write something in
VBA to do this (aka a macro). I'm not a big fan of The Man (tm) but Excel's
VBA interface is excellent. Just make sure you install the VBA help files,
they aren't installed by default.

I think that I can safely conclude that you have not worked in an American
business :-)

^^^^^^^^^^^^^^^^^^^^^^^^^

That may explain the above mentioned situation better than I can.

He's not using Excel to visualize or process images. An IDL program visualizes the images from
QuickTime movie frames, then acquires data from the images and does the important preliminary
processing. He wants to store the pre-processed data from all the frames in a multiple-sheet
format that Excel can read or import, so that he and others can graph/analyze the data using the
spreadsheet functions they know.
