ReapeatMasker only uses E. coli insertion elements

Question

[Ric]

Hi, I used RepeatMasker with different species, but it always only compared to E. coli insertion elements:

wget http://hgdownload.cse.ucsc.edu/goldenPath/hg19/chromosomes/chrM.fa.gz
gunzip chrM.fa.gz

RepeatMasker -species human -s -xsmall chrM.fa

RepeatMasker version open-4.0.5
Search Engine: NCBI/RMBLAST [ 2.2.27+ ]
Master RepeatMasker Database: /usr/local/RepeatMasker/Libraries/RepeatMaskerLib.embl ( Complete Database: 20150807 )

analyzing file chrM.fa

Do I have to use an addition parameter in order to extend the search?

add the -lib option to use specific libraries of repeats

Because it checks in default mode for them. When you want to skip the insertion elements check, you have to give the option -no_is in your string.
