DCA1000EVM: Parsing logic for IQ data from DCA1000EVM using CLI tools

Hi, 

I am trying to parse IQ data from DCA1000EVM and xwr1642, using OOB demo and CLI tools. I used the the logic mentioned in section 9.2 for parsing the data

Mmwave Radar Device ADC Raw Data Capture (Rev. B) (ti.com)

SInce the "fileSize" variable in the code sometimes is not an exact multiple,  numChirps gets decimal points, then the subsequent reshape operation fails. Just wanted to check, is this the right logic for data capture using OOB demo and CLI tools?

Thanks
