  tr = NULL, pix_dim = NULL, poly_det_ord = 3, spike_detect = FALSE,
  x_pos = NULL, y_pos = NULL, plot_title = NULL, last_vol = NULL,
  gen_png = TRUE, gen_res_csv = TRUE, gen_pdf = FALSE,

  bg_shrink = 25)

`data_file`	input data in nifti format, a file chooser will open if not set
`roi_width`	roi analysis region in pixels (default=21)
`slice_num`	slice number for analysis (default=middle slice)
`skip`	number of initial volumes to exclude from the analysis (default=2)
`tr`	override the TR detected from data (seconds)
`pix_dim`	override the x,y,z pixel dimensions (mm) detected from data eg pixdim=c(3,3,3)
`poly_det_ord`	polynomial order used for detrending (default=3)
`spike_detect`	generate k-space spike-detection plot (default=FALSE)
`x_pos`	x position of ROI (default=center of gravity)
`y_pos`	y position of ROI (default=center of gravity)
`plot_title`	add a title to the png and pdf plots
`last_vol`	last volume number to use in the analysis
`gen_png`	output png plot (default=TRUE)
`gen_res_csv`	output csv results (default=TRUE)
`gen_pdf`	output pdf plot (default=FALSE)
`gen_spec_csv`	output csv of spectral points (default=FALSE)
`png_fname`	png plot filename
`res_fname`	csv results filename
`pdf_fname`	pdf plot filename
`spec_fname`	csv spectral data filename
`verbose`	provide text output while running (default=TRUE)
`bg_smooth`	amount to smooth background image before calculating the maximum BG percent metric (default=12mm)
`bg_shrink`	amount to shrink the BG image away from the object to avoid residual object signal in the maximum BG percent metric (default=25mm)
