How do I download the GNU split files for Stimulate?
The Stimulate executables and user's guide are available in a set of consecutively numbered/lettered sections generated by GNU split. These files are intended for downloading by users who have slow internet connections that experience occasional (or regular) interruptions. Thus only those sections interrupted during the ftp download need to be retransmitted. The files are located at: geronimo.cmrr.umn.edu In the directory: /pub/stimulate/stimulate_v5.0/split For example, to reconstruct stimulate_Solaris.Z retrieve all the files sections: stimulate_Solaris.Z.aa stimulate_Solaris.Z.ab stimulate_Solaris.Z.ac Then: unix> cat stimulate_Solaris.Z.* > stimulate_Solaris.Z unix> uncompress stimulate_Solaris.Z unix> chmod +x stimulate_Solaris unix> rm stimulate_Solaris.*FAQ:gsplit.q

What does the error "fatal: libxview.so.3" mean?
The reason you may receive one or both of the following messages when trying to run Stimulate is that your LD_LIBRARY_PATH environment variable is not set or is set incorrectly. fatal: libxview.so.3: can't open file: errno=2 fatal: libolgx.so.3: can't open file: errno=2 The installation script puts the following command into the stimulate script which is used to invoke the stimulate executable: setenv LD_LIBRARY_PATH /usr/openwin/lib This is the default location for openwin. However, if your System Administrator has installed openwin at a different location, you must edit the stimulate script. Another reason you may get these errors is that you did not run the installation script "stimInstall.sh."FAQ:ld_lib.q
Why do I get a "Numerical Recipes run-time error"?
The following error occurs when generating a t-Test map with that has no (i.e. 0.0) variance in either the control or stim periods. Numerical Recipes run-time error... a or b too big, or TMAX too small in BETACF ...now exiting to system... Here at the CMRR always have a bit of noise in our images so this rarely or never happens to us. However, I'll fix this sometime soon and release a version 5.0.1. You can probably work around this problem by generating a mask to eliminate evaluation of pixels with no variance.FAQ:numRecErr.q
What Operating System does my workstation have?
Use the unix command: "uname -s -r" where the option switches are as follows: -r Prints the operating system release level. -s Prints the name of the operating system. Example> uname -s -r SunOS 5.5.1 Note that for Sun workstations the SunOS release level corresponds to the Solaris version as follows: SunOS 4.1 == Solaris 1.1 SunOS 5.3 == Solaris 2.3 SunOS 5.4 == Solaris 2.4 SunOS 5.5 == Solaris 2.5FAQ:os.q
