Origin Ver. and Service Release (Select Help-->About Origin): 8.0 SR6 Operating System: Win7
Hi, I'm working on an analysis template with the import wizard, and I'm not sure how to access a user defined variable to include it in a calculation. I have a header that looks like the following:
10:32:52 AM 06/24/2011 Setpoint = 5.000000 T Current = 0.200000 (uA) Ramp rate = 1.000000 T/min Sample 6-13-11.2-c Current from 1.000000 to 13.000000 Vxx: 16.000000 minus 14.000000 Vxy: 3.000000 minus 15.000000 Dark Resistivity = 57.600000 (Ohms/sq)
I can successfully put the resistivity value into the user variable "Rho", and one thing (among others) that I want to do is a simple calculation 1/(1.6E-19 * Rho * another value I calculate). The problem is the syntax for accessing the variable. I can display the variable in the command window using the command
page.info.user.variables.rho$=
and I can even assign it to a variable (I chose 'aa' just for kicks) and it displays properly when I type aa$= <ENTER>. However, Origin doesn't want to let me do any math with this variable. If I say 10*aa$= <ENTER> I just get the message "#Command Error!' I'm not sure if the variable is the wrong data type (do all imported variables get set to be strings?), or if it has something to do with it being a global variable (that's what the $ indicates?). Any help would be appreciated as I haven't been able to find an answer in the Origin help. Thanks
