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 --- Dr. Klaas Max MDC Berlin Buch Macromolecular Structures and Interactions Robert-Roessle-Strasse 10 13125 Berlin phone +49 30 9406 2265 fax +49 30 9406 2548 ---
