[Insight-users] reading writing multiple dicom files

[Ashish Singh]

Thanks for replying Luis. I found out what was causing the problem in my
code. Btw, I had posted my code before in the list. The link is:
http://public.kitware.com/pipermail/insight-users/2007-January/020588.html
I am trying to read 2D dicom files from a particular directory. These dicom
files may not belong to the same study/series. Then I do some processing on
the individual files and write them to a directory provided through a Qt
GUI.
I have most of this figure out, only a couple of things and I would
appreciate if you could help me with that-
1). How do I get rid of the new instance of pointer to reader and writer
that gets created inside the for loop. Using 'Delete()' gives me errors.
2). How do I set the outputdirectory name for the writer. There is a
'setoutputdirectory ' function for writing the series, but there isn't one
for the regular writer. I am supplying the writer with the file names and
want them all to go to a specific directory provided by the user from the
GUI. How do I do it?

Thanks,
Ashish
