Dear colleagues,
I have problems installing external tasks to CCP4i. This particularly
involves ARP/wARP 7.0.1. Despite the error message shown by the
install/uninstall form after setting the location of the task archive file,
I assume that the problem is due to an error or incompatibility with my work
surrounding concerning the install functions in CCP4i.
The following error message shows up when I specify the path to the installer
archive::
Failed to unpack and/or read contents of
/home/klaas/ccp4/arp_warp_7.0.1/ARP_wARP_CCP4I6.tar.gz. This may not be a
valid CCP4i package.
At the same time, the following error messages show up on the console:
UnpackTaskArchive: uncompress failed to create
"/tmp/klaas/install_ARP_wARP_CCP4I6/ARP_wARP_CCP4I6.tar"
ExamineTaskArchive: failed to unpack temporary copy of
/home/klaas/ccp4/arp_warp_7.0.1/ARP_wARP_CCP4I6.tar.gz
The following steps were tried out to overcome this problem:
1.) I checked the location of the archive - it was exactly as specified.
2.) I manually extracted the archive (using unpack and tar -xvf) - this worked
but
unfortunately didn't help to install the ARP/wARP package.
3.) I copied the extracted archive into the specified temp directory but the
installation task complained that the respective directory has to be empty
to install new tasks and removed the content. Thereafter the original error
message reappeared.
4.) I checked the existence of the temp directory (/tmp/klaas). It existed and
was
read and writeable. I even made it writeable to everyone but this didn't solve
the problem.
5.) I changed the temp directory to /home/klaas and made this directory
accessible to everyone, this didn't help either.
6.) I tried to manually install the task archive to ccp4i running the
CCP4i_packages_utils.tcl
script from the console ( tclsh CCP4i_packages_utils.tcl ARP_wARP_CCP4I6
LOCAL ARP_wARP_CCP4I6.tar.gz). No error message showed up but nothing
happened either.
I am using CCP4i on a novel installation of ubuntu 8.10 using the tcsh. The
CCP4 package was compiled from the source code and installed locally on my user
account. It turned out to be functional apart from the problem reported here. I
already successfully ran contact, phaser, baverage, matthews & refmac5 using
the CCP4i interface.
Taken all these informations into account I assume that the cause of the faulty
installation task is probably located in the CCP4i_packages_utils.tcl script,
which hosts the procedures UnpackTaskArchive and ExamineTaskArchive, probably
in context with my operating system or work surrounding as otherwise many
people would have noticed similar difficulies.
In fact, however, there are two additional postings that describe similar
problems when installing tasks:
1.) by Gerlind Sulzenbacher on Mon, 26 Jun 2006, involving CCP4i 6.0.1 &
ARP/wARP: http://www.mail-archive.com/ccp...@dl.ac.uk/msg03190.html
2.) by Roberto Bossi on Mon, 07 Apr 2008, involving CCP4i 6.0.2 & Mr. Bump
http://www.mail-archive.com/ccp4bb@jiscmail.ac.uk/msg05535.html
Under these threads I have found not suitable solution.
Any suggestions are greatly appreciated, I urgently need ARP/wARP.
Thank you very much for your time and support,
cheers,
Klaas
