checksums do not match for .csv.gz files

[horwitzr]

The checksums for the following files do not match what is on https://physionet.org/content/eicu-crd/2.0/SHA256SUMS.txt: apacheApsVar.csv.gz apachePredVar.csv.gz carePlanEOL.csv.gz respiratoryCare.csv.gz vitalAperiodic.csv.gz vitalPeriodic.csv.gz

I downloaded all of the data from https://physionet.org/content/eicu-crd/2.0/ using the "Download the Zip file" link. When I tried the checksums on my Mac using

md5 apacheApsVar.csv.gz

I get "MD5 (apacheApsVar.csv.gz) = bac59eb77b3635c0774076e4e5df3506", which does not match "4dfa6d3d36c3f9a1853027e0ca84668cd6dd4dfae24c330e0ceae324cbfc41b4'

The same occurs for the other five files, as well.

Hi @horwitzr,

I think you're using md5 hashes, and the hashes on physionet are sha256. Trying running:

sha256sum apacheApsVar.csv.gz

I'm not sure if OSX uses a different command than linux (maybe sha256 ?), but that works in linux. I just checked the above file and it matches.

Hi @jraffa,

Thank you so much; you are correct. They do match now. However, I'm having some problems unzipping those files. When I double click on a file such as apacheApsVar.csv.gz in Finder, I get an error message that says, "Unable to expand apacheApsVar.csv.gz into eicu-collaborative-research-database-2.0. (Error 79 - Inappropriate file type or format.)

My original problem could have been summarized by saying that those initial six files were not unzipping although the others were. The solution was to use gunzip, not double click on them in Finder.
