Question

[shoujun.gu]

I tried to use kallisto to align and quant my RNA-Seq data after built kallisto index, i tried to quant my data by typing:

kallisto quant -i $REF -o kal1 $R1 $R2

And I got an error:

[quant] finding pseudoalignments for the reads ...terminate called after throwing an instance of 'std::system_error'
  what():  Enable multithreading to use std::thread: Operation not permitted
Aborted (core dumped)

Could someone help me to solve this error?

I'm using kallisto 0.43.1 on Ubuntu 16.04.2 LTS. Thanks!

after some google, i found it's a compiling problem. My kallisto was installed from brew. After I remove the old version, and directly installed from github, problem solved.
