[MINC-users] mincconcat error

[Audette, Michel]

Hi Claude, 

as you suggested, I played around with the files.tmp file, to ascertain the effect of deleting some entries, and it does turn out that mincconcat is sensitive to the number of entries. With 1000 mnc files 

full_gray/0999.mnc
...
full_gray/0001.mnc
full_gray/0000.mnc


I get: 

maudette at icaw164059:/data/KoreanVisible> mincconcat -clobber -filetype -filelist files.tmp -concat_dimension zspace -sequential full.mnc
Processing:.. 
...(skipping...)
..Done

With slightly more than that...
full_gray/1328.mnc
full_gray/1327.mnc
...
full_gray/0001.mnc
full_gray/0000.mnc

I hit a size limit somewhere: 

maudette at icaw164059:/data/KoreanVisible> mincconcat -clobber -filetype -filelist files.tmp -concat_dimension zspace -sequential full.mnc
Processing:.mincconcat: ncx.c:1716: ncx_put_size_t: Assertion `*ulp <= 4294967295U' failed.
Aborted

I should emphasize that I am working with 64-bit Suse 10 Linux. 

Cheers, 

Michel

Hi Michel,

I'm using mincconcat for 7400 slices and it works. In minc2, of course.
Here is my command:

mincconcat -clobber -filetype -filelist files.tmp -concat_dimension yspace -sequential full.mnc

You may need to change the concat_dimension (may not be yspace for you). 
You should also disable internal file compression if concatenation is too
slow (setenv MINC_COMPRESS 0).

Try this and let me know. It could also be some bug.

Claude
