lastz error

[jigaoxiang]

Hello professor: When I use the lastz to get _lastz.txt file using `lastz .genomic.fa[multiple] .genomic.fa[multiple] --chain --format=general:name1,strand1,start1,end1,name2,strand2,start2,end2 > _lastz.txt` some problem like below happen: "FAILURE: in add_segment() table size (4,869,542,152 for 101,448,794 segments) exceeds allocation limit of 4,294,967,279; consider raising scoring threshold (--hspthresh or --exact) or breaking your target sequence into smaller pieces" look like "raising scoring threshold" will working? the default of "--hspthresh" is 3000 ,so how many can set ？ could you give me some advice! Thank you very much!

Hi, lastz is not needed to run SVMU. Just run nucmer as shown in the Readme and run svmu on the delta file. If you encounter an issue, let me know.

Thanks for your response! but this is another error when i use directly the outputfile of nucmer to run svmu Segmentation fault (core dumped) the code what I use svmu *_numcer.delta ref.genomic.fa sample.genomic.fa samvsref”svmu *_numcer.delta ref.genomic.fa sample.genomic.fa samvsref

Hi, Have you solved this problem?I have encountered the same error as yours.
