ggir.summary: Description of all accelerometer files in the GGIR output
In postGGIR: Data Processing after Running 'GGIR' for Accelerometer Data

Description of all accelerometer files in the GGIR output and this script was executed when mode=2 in the main call.

ggir.summary(
  bindir = NULL,
  outputdir,
  studyname,
  numericID = FALSE,
  sortByid = "filename",
  subdir = "summary",
  part5FN = "WW_L50M125V500_T5A5",
  QChours.alpha = 16,
  filename2id = NULL,
  desiredtz = "US/Eastern",
  trace = FALSE
)

`bindir`	`character` Directory where the accelerometer files are stored or list for the purpose of extracting the bin file list. Default=NULL when it is not available and therefore the bin file list is extracted from the /meta/basic folder of the GGIR output.
`outputdir`	`character` Directory where the GGIR output was stored.
`studyname`	`character` Specify the study name that used in the output file names
`numericID`	`logical` Specify if the ID is numeric when checking ID errors in part2. Default is FALSE.
`sortByid`	`character` Specify the name of "ID" for each accelerometer file in the report of part2. The value could be "newID","id" and "filename". Defaut is "filename".
`subdir`	`character` Sub-directory where the summary output was stored under the current directory. Defaut is "summary".
`part5FN`	`character` Specify which output is used in the GGIR part5 results. Defaut is "WW_L50M125V500_T5A5", which means that part5_daysummary_WW_L50M125V500_T5A5.csv and part5_personsummary_WW_L50M125V500_T5A5.csv are used in the analysis.
`QChours.alpha`	`number` Minimum required number of valid hours in day specific analysis as a quality control step in part2. Default is 16 hours.
`filename2id`	`R function` User defined function for converting filename to sample IDs. Default is NULL.
`desiredtz`	`charcter` desired timezone: see also http://en.wikipedia.org/wiki/Zone.tab. Used in g.inspectfile(). Default is "US/Eastern".
`trace`	`logical` Specify if the intermediate results is printed when the function was executed. Default is FALSE.

Four files were written to the specified sub-directory

`studyname_ggir_output_summary.xlsx`	This excel file includs 9 pages as follows,
`page 1`	List of files in the GGIR output
`page 2`	Summary of files
`page 3`	List of duplicate IDs
`page 4`	ID errors
`page 5`	Number of valid days
`page 6`	Table of number of valid/missing days
`page 7`	Missing patten
`page 8`	Frequency of the missing pattern
`page 9`	Description of all accelerometer files
`page 10`	Inspects accelerometer file for key information, including: monitor brand, sample frequency and file header
`studyname_ggir_output_summary_plot.pdf`	Some plots such as the number of valid days, which were included in the part2a_studyname_postGGIR.report.html file as well.
`part24daysummary.info.csv`	Intermediate results for description of each accelerometer file.
`studyname_samples_remove_temp.csv`	Create studyname_samples_remove.csv file by filling "remove" in the "duplicate" column in this template. If duplicate="remove", the accelerometer files will not be used in the data analysis of part 5-7.
