This is probably a memory problem. There is a section on this in the FAQ:
http://www.sanger.ac.uk/Software/Artemis/faqs.shtml#faqs --------------------------- 4.Why does Artemis run out of memory on Windows even though the machine has lots of memory? Normally the Java virtual machine artificially limits the amount of memory that Artemis can use. The fix is as follows: Create a shortcut to the Artemis JAR file. Edit the properties of the shortcut and add "java -mx250m -jar " to the start of the Target: field. -mx250m sets the maximum memory Java will allocate to Artemis. We recommend choosing a number that is about 50 megabytes less than the total amount of memory in the machine (to allow for the overhead of windows and the Java virtual machine). You will need to use the shortcut to run Artemis from then on. -------------------------- yours, Julian Parkhill. > "lekap@" wrote: > > Hello, there, > > I am trying to read Y. pestis CO92 genome in Artemis on WinXP or > Win2000 1Gb RAM /256 Mb. > It displays only the feature panel and the middle panel.
