Hi Goi, please remember to post to the freesurfer list. Thanks! The max
psd depends upon how long it takes for the HRF to return to baseline
(and do not related to the TR). This is usually something like 20 sec +
the duration of your stimulus.

Dear Prof, Previously I was having problems running optseq, and so
have left it off for a while. I have went back to try again, and
managed to get it to churn sequences. Thank you very much for your
advice and patience.
I have one more query: How much do you think we should set the psdmax
if we have TR of 1, and 2?
Thanks for your advice!

are you running "optseq" or "optseq2"? It should be optseq2. You
may need to make it executable (looks like you have the right
chmod command line, but don't put the "./" before it). I can't see
what you are trying to accomplish with the find command. Once you
have it exectuable, you should be able to run it with ./optseq2
(if it is in the current directory).

Dear Doug,
Thanks so much for your reply. I've downloaded VirtualBox, and
have also loaded Ubuntu linux OS into the VirtualBox. I managed
to put in the linux version of optseq2, but was unable to get it
to run or locate the file. I've ran commands via the terminal
using terms such as ./optseq2 , ./chmod a+x optseq2, find~/ -type
f -name "optseq2". However, the messages that I get are either
"optseq: command not found" or "No such file or directory.". I
suspect this could be due to my limited knowledge on using linux OS.
Do you happen to have a manual that you could share on how to
load Optseq?
Any advice would be very helpful.
Thanks much!

Hi Goi khia, it does not really run under windows. The
version there is if you have a program called CygWin which is
a linux emulator. We have not used that in a long time. You
can do the same thing with VirtualBox (another linux emulator
that runs under windows).

Dear Prof Greve,
I am trying to download Optseq from
http://surfer.nmr.mgh.harvard.edu/optseq/ on my Windows
machine (Windows 7), but an error message keeps coming up,
that cygwin1.dll is missing.
I've downloaded the cygwin file from cygwin.com
<http://cygwin.com>, but am still unable to download Optseq,
and the same error message appears.
Do you have any advice on how I can try to resolve this?
Thanks much!
