Java.lang.OutOfMemoryError: Requested array size exceeds VM limit

[weipenegHU]

I came across this problem when running the TreeAnnotator. I have changed the -Xmx of TreeAnnotator to 10GB but it did not work. Here are some information that may be helpful.

input tree size: 3.2G Burn in: 1,000,000 states Targe tree type: Maximum clade credibility tree Node heights: Median heights

Hello, I also encountered the same problem, how do you solve it later

[rambaut]

You will likely need much more than 10GB to load this tree file. I suggest down sampling it first using LogCombiner.

[liamxg]

reset the xml file file for <= 10000 trees?

[rambaut]

That won't be necessary. Use LogCombiner in the BEAST package to resample your existing log files to a sparser sample. https://beast.community/logcombiner

got it, thanks.
