How to decompress Cityperson dataset?

[scangit]

I try to decompress cityperson dataset:
cat Citypersons.z01 Citypersons.z02 Citypersons.z03 Citypersons.zip > c.zip unzip c.zip

But I got the following error:
Archive: c.zip error: End-of-centdir-64 signature not where expected (prepended bytes?) (attempting to process anyway) warning [c.zip]: zipfile claims to be last disk of a multi-part archive; attempting to process anyway, assuming all parts have been concatenated together in order. Expect "errors" and warnings...true multi-part support doesn't exist yet (coming soon). warning [c.zip]: 9437184000 extra bytes at beginning or within zipfile (attempting to process anyway) file #1: bad zipfile offset (local header sig): 9437184004 (attempting to re-compensate)

I can only get partially unzipped files:
ls Citypersons/images/train/ tubingen ulm weimar zurich

Can you provide the checksum of all part of Citypersons?

@scangit you can check #139
You may try to download all .zip file again

I am still getting the same problem after following #139. Only part of the files got unzipped.

Solved it!! Needed to repair the zip file after concatenation.

Thank you for your reply. I can decompress it correctly now. The command I use is:
zip -FF Citypersons.zip --out c.zip
then
unzip c.zip
