Off topic:fasta header trimming in a multifasta

Question

[ignazio.fontana]

Hi,

I have a multifasta with the transcripts of an assembled rnaseq and the header of each fasta is like this:

>TRINITY_DN5895_c0_g1_i1 len=288 path=[152:0-287] [-1, 152, -2]

I want to trim each fasta header to:

>TRINITY_DN5895_c0_g1_i1

Can you help me? Thanks
