extracting the corpus zip files

[Suzan Verberne]

Dear all,

Maybe I missed another topic on this, but I have problems extracting the corpus zip files (on Linux).

I first tried 'unzip part1.zip'

But got:

End-of-central-directory signature not found.  Either this file is not

  a zipfile, or it constitutes one disk of a multi-part archive.  In the

  latter case the central directory and zipfile comment will be found on

  the last disk(s) of this archive.

After googling I found this solution: 'jar xvf part1.zip' and that seemed to work at first but then I get:

created: part1/

 inflated: part1/attra0843_12.dat

 inflated: part1/bestb0834_12.dat

 inflated: part1/cadth0844_12.dat

 inflated: part1/cks.n0835_12.dat

java.io.EOFException: Unexpected end of ZLIB input stream

        at java.util.zip.InflaterInputStream.fill(InflaterInputStream.java:240)

        at java.util.zip.InflaterInputStream.read(InflaterInputStream.java:158)

        at java.util.zip.ZipInputStream.read(ZipInputStream.java:163)

        at java.util.zip.ZipInputStream.closeEntry(ZipInputStream.java:109)

        at sun.tools.jar.Main.extractFile(Main.java:954)

        at sun.tools.jar.Main.extract(Main.java:870)

        at sun.tools.jar.Main.run(Main.java:260)

        at sun.tools.jar.Main.main(Main.java:1167)

The same for the other parts, although some get further than others.

What do I do wrong?

Thanks!

You might want to check if you have downloaded the complete file
(i.e. compare the file size of your physical file with the actual file size).
For incomplete zip archives, uncompressing the archive will fail with
the error message you got.

Thanks! That seems to be the probleem indeed!

I now succeeded in extracting all files, except for part2.zip
'jar xvf part2.zip' gives:

created: part2/
java.io.IOException: Push back buffer is full
at java.io.PushbackInputStream.unread(PushbackInputStream.java:232)
at java.util.zip.ZipInputStream.readEnd(ZipInputStream.java:374)

at sun.tools.jar.Main.run(Main.java:260)
at sun.tools.jar.Main.main(Main.java:1167)

And the only inflated file is clini0836_12.dat

Anyone recognizes this problem?

Hi Suzan,

Sorry for the delay replying. We just tried again to unzip it with the command "unzip" on ubuntu and it worked fine (2 of us tried this). 

I got an error with Open suse on another computer, similar to the one you got in your first message, and managed to unzip it with the graphical interface (I mean not through command line).

Let us know if that helps. 

Best,

Lorraine
