Hello, I am a windows user. I have installed cygwin and I have am following the installation instruction for windows on the FSL installation webpage. "In the Cygwin terminal: - *cd /usr/local * - *tar xvfz fsl-*.tar.gz (don't use WinZip to do this unpacking - it can corrupt the files!) * - echo 'export FSLDIR=/usr/local/fsl; . ${FSLDIR}/etc/fslconf/fsl.sh; export PATH=${FSLDIR}/bin:$PATH' >> ~/.bash_profile (make sure you type that *EXACTLY* including the "." and the spacing!!) " I have been able to perform the above two commands in BOLD successfully. However, I get the following bash command when I type third command (in RED ) bash:/etc/fslconf/fsl.sh: No such file or directory bash : export: '{FSLDIR}=/usr/local/fsl': not a valid identifier bash: /C:/cygwin/usr/local/fsl/etc/fslconf/fsl.sh: No such file or directory bash: /C:/cygwin/usr/local/fsl/etc/fslconf/fsl.sh: NO suhc file or directory I have typed the exact sentences as written in the FSL website. When I physically check my computer using windows explore, I see the folders as they should be ie: C:/cygwin/usr/local/fsl/etc/fslconf/fsl.sh. - The main problem is I am trying to chnage the default output to ANALYZE and I am not able to access the fsl.sh file. - I also am not sure if I have setup the $ FSLDIR environment correctly and how do I verify this? Please reply and any suggestions will be greatly appreciated! Thanks,
