Hello. I am a student of Chonnam National University in Korea.

I was running this command.

trinityrnaseq-2.0.6/util/abundance_estimates_to_matrix.pl --est_method RSEM hanwoo_cmale_i_r1.genes.results hanwoo_cmale_i_r2.genes.results hanwoo_cmale_i_r3.genes.results

I was faced with this problem

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
    LANGUAGE = (unset),
    LC_ALL = (unset),
    LANG = "ko_KR.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
