ReadGem: Read raw Gem data

In gemlog: File Conversion for 'Gem Infrasound Logger'

Description

Reads raw Gem data into R. To write segy files, use Convert.

Usage

ReadGem(nums = 0:9999, path = './', SN = character(), units = 'Pa',
bitweight = NaN, bitweight_V = NaN, bitweight_Pa = NaN, alloutput =
FALSE, verbose = TRUE, requireGPS = FALSE)

Arguments

nums	File numbers to convert.
path	Directory in which raw data files are contained.
SN	If set, only read files of this serial number.
units	For unit conversions: should the output be in V, Pa, or counts?
bitweight	If set, override the default bitweight for this logger in the current configuration.
bitweight_V	If set, override the default V bitweight for this logger in the current configuration.
bitweight_Pa	If set, override the default Pa bitweight for this logger in the current configuration.
alloutput	Include raw data in the output, in addition to the processed data.
verbose	Provide verbose output.
requireGPS	Require GPS strings to perform the conversion.

Value

t	sample times (POSIXct)
p	samples (in whatever units were set by user)
