How to change the job status for a filter chunk

I want to change the status of all the jobs corresponding to the second chunk. Following the guidelines of auto-submit I applied:

autosubmit setstatus a148 -fc [ 20150101 [ 1 [2] ] ] -t READY -s

But it gives an error: unrecognized arguments: 20150101 [ 1 [2] ] ]

I do not know what is wrong, any idea @dmanubens?
