error when trying to follow tutorial

[mocherry]

Dear all,

I started to follow the Salmon "Real data example" on https://combine-lab.github.io/salmon-tutorials/2021/ont-long-read-quantification/

Everything goes fine up to:
minimap2 –t 8 –a -x map-ont –p 1.0 –N 100 minimap2_spike_index SRR6058582.fastq

when I get the following error:
[ERROR] failed to open file '–t': No such file or directory

???

Help would be appreciated. Thanks and best,
Matthias
