i want to test an example in STM32F4xx StdPeriph_Lib Examples that explains ADC3 using channel7 with DMA

there is Configure ADC Channel7 pin as analog input

  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AN;
  GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_NOPULL ;
  GPIO_Init(GPIOF, &GPIO_InitStructure);

now i can not find
GPIOF_pin_9 on the discovery board
what should i do now? can i replace it with another pin from another port?
