That's great!
Enjoy FSL then; and beware that, depending on what you are trying to do, even 1.5GB (ram+swap) may prove to be not enough... (it really depends on what you are trying to do, some operations are not so demanding and you may do fine with the 500MB of RAM available, but others may cause trouble by exhausting the 1GB swap too. I think this is likely to happen, for example, if you do a 'bet' with the -B option, when more than 2GB of RAM may be required for some T1 images. You can visually see the amount of memory used with "System Monitor", including the swap portion.)
Best,
Silviu

Dear Silviu,

thank you for answer and your help!! - Since my first message I had managed to download FSL 4.1.9 and Feeds did not work with this version, too. But now I found out what was the problem: The swap-partition was too small - my old laptop only has about 500 MB RAM and the swap-partition also had only about 500 MB. Now swap has about 1GB and the tests are all right!

Thank you and have a nice week!
Christina

I have not run the feeds test in a while (since i installed FSL 2+ years ago), but if you give me the version number, i can try to see if the problem gets replicated on my computer (one of these days)...
