[vtkusers] Re: DICOM2 to vtk *.raw !!!!Error!!!Help!!!

[Peter]

hi JJ,
   i guess u r doing some assignment for Cranio-Facial Visualization :P.

first, the file extension of dc and dcm does not matter at all. if you
r uneasy about the extension , u can just go to ur windows command
line (assuming u r using windows) and rename all files with wildcard.

    u may refer the medical1.tcl, but i bet if u just borrow some
lines from there it won't work at all...

there is a clumsy solution if you dare to try.

change all you imxxx.dc.raw to im001....im123  without any exention.
then all the files can be loaded. while u might need to change one
file by one file,

alternatively, u may go back dicom2 website, see there is a renmae
function for dicom2, which means u can change the name of resulting
files.

for example
u can set ur file name like test-1.raw test-2.raw..... test-123.raw  rather than
im001.dc.raw .......im123.dc.raw.

and there is another very critical issue, r u really sure about the
dataspacing of the raw ??? i guess u just randomly put some numbers
there.... so please think a way to find the dataspacing....

by the way ,the assignment takes lots of time to search and read...
that is what i did....

please try harder

hope it helps

Yours
Pan
