When loading a PacketInfo_Vel#.m file, the variables are:

NodeIDs <2x10000>

-1st row is the partner ID

-2nd row is the Antenna ID.

-10,000 is the total number of packets

PacketData <7x10000>

-1st row is time stamp in seconds

-2nd row is time stamp in microseconds

-3rd is goodPackets

-4th is otherBadPackets

-5th is partnerBadPackets

-6th is rxBytes

-7th is txBytes

Sec <1x10000>

-1st row is time stamp in seconds

USec <1x10000>

-1st row is time stamp in microseconds

chanBB <1x10000>

-1st row is chanEstsStruct agc_BB

chanRF <1x10000>

-1st row is chanEstsStruct agc_RF

chanEstsI <64x10000>

-Rows represent chanEstsStruct I component

chanEstsQ <64x10000>

-Rows represent chanEstsStruct Q component

pkStatus <1x10000>

-1st row is the Packet Status
