Trace Data table

Requirement level: optional

Summary

This table is used to document properties that are globally associated with individual Traces rather than individual bright Spots (e.g., Physical coordinates, RNA transcription, or Allele). These are properties that are shared by all bright Spots that constitute a Trace.

Each row in the table corresponds to an individual Trace and is indexed by a unique Trace_ID that links the data reported in this table with data stored in one of the other tables (e.g., DNA-Spot/Trace Data core table, RNA-Spot Data table, etc.).

Example

##FOF-CT_version=v0.1
##Table_namespace=4dn_FOF-CT_trace
##XYZ_unit=micron
##intensity_unit=a.u.
#^allele: This field records the Allele to which this Trace was mapped. This can be one of the following values: BL6, CAST.
#^RNA_A_intensity: This records the intensity of the nascent RNA A expression signal associated with this Trace.
#^NL_distance: This field records the distance of this Trace to the Nuclear Lamina.
#additional_tables: 4dn_FOF-CT_core, 4dn_FOF-CT_cell
##columns=(Trace_ID, allele, RNA_A_int, NL_distance)
1, BL6, 43253, 0.235
2, CAST, 40001, 0.563
3, BL6, 1000, 0.135
4, CAST, 1500, 0.633

#Software_Description:

A free-text, description of this Software. This description should provide a detailed understanding of the algortithm and of the analysis parameters that were used, in order to guarantee interpretation and reproducibility.

ChrTracer3 software was developed for analysis of raw DNA labeled images. As an input, it takes an.xlsx table containing information and folder names of the DNA experiment. As an output, it returns tab delimited.txt files with drift-corrected x, y, z positions for all labeled barcodes. These can be used directly to calculate the nm scale distances between all pairs of labeled loci. The current version of the software as of this writing is ChrTracer3.
