Dear CCP4bb, Sorry for the non-CCP4 related question.
I am running HKL2000 (ver 0.98.698m) on an iMac (OSX 10.5). On starting up the software the following message is displayed:- "Total amount of memory found: 2041 MB (required by HKL-2000; 256 MB) Could not check system resources Please run commands: uname -a [HKLPATH]/hklsysinfo M memory [HKLPATH]/hklsysinfo M swap [HKLPATH]/hklsysinfo M memory limit Error: swap amount not valid" ( On running the above commands and the output is: i) uname -a: Darwin balvinder-dhaliwals-imac.loca 9.0.0 Darwin Kernel Version 9.0.0: Thu Oct 11 19:23:39 PDT 2007; root:xnu-1228~3/RELEASE_I386 i386 ii) HKLPATH]/hklsysinfo M memory: Total: 2036.23 Used: 703.352 Free: 1312.78 iii) [HKLPATH]/hklsysinfo M swap: error: An error has occured while getting swap info iv) [HKLPATH]/hklsysinfo M memory limit: error: Unlimited datasize, but unable to get physical limits error: An error has occured while getting memory info ). For the most part, HKL2000 runs well; I am able to display my images, peak search, process data, scale data, etc, etc. However, when I try to open up a 'zoom window' in XDisplayF, HKL2000 crashes. Unlimiting the memoryuse, stacksize and datasize was ineffective. Increasing the swap space was also unsuccessful. My question is: Do I need to allocate more virtual memory or does the problem lie elsewhere? Balvinder Dhaliwal (Randall Division of Cell & Molecular Biophysics, King's College London).
