Could someone please tell me what would cause the error below?
multiz.v11.2: ckalloc: request for negative space.
Some of my MAF files ran good, but others had this error. I could not fingure out what difference between them..
Another error also occured "segmentation fault (core dumped) " when I running multiz.
There is no magic wand in solving this problem. You need to look into the files and tell us what are the differences between those that worked and those that didn't. Is it file size? Were they made by the same program? It is like in procedural shows on TV: tough to conclude anything definitively without information.
On the surface, it seems like a memory issue.
Thank you so much for your reply. The multiz program which downloaded from this page(https://github.com/multiz/multiz)(multiz.v11.2), and I use the same command(multiz M=1 _MZ_2222467_left.maf5 _MZ_2222467_right.maf5 0 _MZ_2222467_C3 _MZ_2222467_C4 >> /_MZ_2222467_MZ5, this command reported the error segmentation fault (core dumped) ) to run the multiz except for the input file, the details about the input file as shown in this figure.
the input file which does not occur error is
I think it may have nothing to do with file size. I use the mafSplit to split maf files by chr and then run multiz again. But the problem doesn't seem to be solved.
See: https://github.com/multiz/multiz/issues/4
This appears to be an unresolved issue.
Yes, i see the problem, so I want to ask if there are any experts who can solve this problem
Excuse me, do you know of any software that can do something like multiz to merge maf files
