Naccess V2.1.1 - Solvent accessible area calculations

Downloading information - Academic users

Industrial Users: for more information please visit XIP

Please read the following instructions carefully

• 1) To download the program, select one of the links below.

  gunzip, then decrypt with crypt - naccess.tar.gz.enc.gz	crypt version
  gunzip, then decrypt with des - naccess.tar.gz.des.gz	des version
  gunzip, decrypt with mcrypt - naccess.tar.gz.nc.gz	mcrypt version
  gunzip, decrypt with rar - naccess.rar.gz	rar version

  You will receive a compressed tar file via http containing everything you need. The tar and rar files have been encrypted or password protected. You need to get a decryption key to decrypt the file. See later.

• 2) Download the Confidentiality Agreement

  We ask users to complete a a short Confidentiality agreement. Please print it out, sign it and return it to us via normal mail (Not email or fax please!).

• 3) Obtain the decryption key.

  To get this key, please send an email to me (simon.hubbard@manchester.ac.uk) and I will return the key to you. I will only send out the key if you send me an email asking for it and not when you send the Confidentiality agreement by normal mail.

• 4) Decrypt the file

  First, you need to gunzip the file. We've added this extra layer to get around some download issues with Firefox via http. Apologies for this extra step, but it means you need to unzip (gunzip) the files before decrypting and unpacking the tar archives etc.

  To decrypt the file you have downloaded use the standard Unix command crypt:

  crypt "key" < naccess.tar.Z.enc > naccess.tar.Z
  

  or, if you don't have "crypt" (ie RedHat) then you can get the "des" version and use the "des -d -k key" command:

  des -d -k "key" naccess.tar.gz.des naccess.tar.gz
  

  I have also added an mcrypt version since most systems don't seem to have crypt anymore.

  mcrypt -d -k "key" < naccess.tar.gz.nc > naccess.tar.gz
  

  (well, thats how mcrypt behaves on my Suse system!) I would be most grateful if users ensured they had tried all possibilities to decrypt the file using one of the above approaches, as I do not offer support on how to use linux or unix systems. Thats down to you ! I suspect your local sys admin people will be faster to respond and less rude than I will be :-)

  Also, the tar file includes the README file which you can preview here to get more of an idea about the program before downloading it.

  Finally, the common archiving utility RAR also has password protection available, so there is another easy way to get the program.

  rar e -p"key" naccess.rar 
  

  Apart from the rar version, once you have downloaded the file, you need to untar and unzip it. To unpack the program, type:

  zcat naccess.tar.Z | tar -xvf -

  Or

  gzip -dc naccess.tar.gz | tar -xvf -

  which will put all the files into a directory called /naccess2.1.1
