Troubles with 'self'

[Richard Speaker]

I'm somewhat new to Python... and programming in general.  I know enough to be dangerous for sure. I have a feeling the solution to this is simple.  I'm having trouble getting 'self' to initialize or work in a class application. I keep getting the message:
   
      LogFile = self.BasicSummary ( )
NameError: name 'self' is not defined
   
  Code looks like this:
   
  from data_decode import *
  class DataAnalysis:
        
        def PainInTheArse ( self , i , InvI ):
                """This is a filter I made to overcome
                some problems I was having with sine wave
                analysis"""
                TemporaryData = [ ]
                for a in range ( int ( InvI [ i ] ) , len ( InvI ) ):
                        if a < 0:
                                a = 0
                        b = a + 1
                        try:
                                TemporaryData.append ( InvI [ a + i ] )
                                if ( InvI [ b + i ] < 0 and InvI [ b + i + 1 ] > 0 ):
                                        TemporaryData.append ( InvI [ a + i + 1 ] )
                                        break
                        except IndexError:
                                continue
                return TemporaryData
          def GetTheInvIData ( self , InvI ):
                  """"Function determines zero-crossing, and then
                calculates the +/- peaks to get an average """
                CurrentMaxList = [ ]
                CurrentMinList = [ ]
                for i in range ( 0 , len ( InvI ) ):
                        try:
                                if ( InvI [ i ] <= 0 and InvI [ i + 1 ] > 0 ):
                                        TemporaryData = self. PainInTheArse ( i , InvI )
                                        BetterData = self.FilterTheBS ( TemporaryData )

                EstPeak = InvIPeakToPeak / 2

any and all advice is welcome
