Marc, If you are predicting a large multi-way table then the memory requirement can get quite large. In the first instance I would try a series of smaller predictions using just a few levels (ie using the 'levels' argument) of one or more of the factors. The bug is that under some circumstances it doesn't always know when it needs more memory for prediction workspace. The value you have given does seem uncommonly large, if you like send me a sanitised version of the data and the call and I'll take a look. Dave. ________________________________ From: ASReml users discussion group [mailto:ASREML-L@DPI.NSW.GOV.AU] On Behalf Of moragues Sent: Friday, 5 February 2010 3:00 AM To: ASREML-L@DPI.NSW.GOV.AU Subject: Re: Predict in ASReml-R leads to 'memory not mapped' crash Thanks Dave. I tried adding pworkspace=Xe6 to my code, being X a multiple of 8. So far this has been unsuccessful (I went up to 160e6, which is over 1 Gb). Is there anything else I can try? Is this bug only in ASReml-R? Let me know whether this is the right place to discuss this issue. Thanks!
