[Freesurfer] Number of Time points

Hi ,

I am basically trying to get an output with 300 lines and the events "one", "two"..."seven" and "null" to be distributed in those 300 points. But when I get the output, I get more than 300 lines and the number of "null" lines in the output is variable(i.e., the 2 output files ex-001.par and ex-002.par both show different number of lines of output with variable number of "null" lines). I slightly changed the code and still I don't get the desired output. So, in a nutshell, I need 300 lines of output with all the events and "null" in those 300 lines. Can you let me know what I should be doing now?

The code is as follows:

optseq2 --ntp 300 --tr 2 \

...

...

    --psdwin 0 20  \
    --ev one 2 20 \
    --ev two 2 15 \
    --ev three 2 15 \
    --ev four 2 50 \
    --ev five 2 50 \
    --ev six 2 50 \
    --ev seven 2 50 \
    --nkeep 2 \
    --o ex \
    --nsearch 10
