Software

FCSExtract
FCSExtract utility reads Flow Cytometery Standard (FCS) data from a binary FCS file and converts it to an ASCII text format, which can be read by a variety of software analysis packages.  [Windows]  An example of working with this data in R is provided.  [UNIX or Windows]   FCSExtract and FCSViewer are not related in any way and work on entirely different FCS data files.

FCSViewer

FCSViewer utility reads Fluorescence Correlation Spectroscopy (FCS) data, a proprietary Zeiss format, and displays the two channels of data over a specified time interval. Updated to work with new Zeiss ConfoCor 3 data format, as well as older ConfoCor 2 format.   [Windows] FCSExtract and FCSViewer are not related in any way and work on entirely different FCS data files.


HemavetCSV
HemavetCSV utility creates a single comma-separated values (CSV) file with summary information from a directory of Hemavet files.  [Windows]  Available on request.

Lomb-Scargle

Detecting periodic patterns in unevenly-spaced gene expression time series
using Lomb-Scargle periodograms.  R Code.  [UNIX or Windows]


PeakFinder
PeakFinder was developed to find cohesin binding sites represented by the peaks in yeast chromatin immunoprecipitation (ChIP) microarray data, but can be applied to plot any measurement against a parameter such as genome coordinate, to interactively analyze the measurement plot, and to annotate the peaks on the basis of local properties of the curve.  [Windows]

TiffTags
TiffTags displays the "tag" fields in a TIFF (tagged image file format) file. TiffTags was created to troubleshoot problem TIFF files and implement code in Windows to display certain TIFFs. [Windows]

TweenMotif
TweenMotif is an interactive Windows program for visualizing the locations of a specified target motif within a set of sequences, as well as the gaps between the repeating motifs. The program creates a summary table of the frequency counts of the gap sequences that can be pasted into an Excel spreadsheet for further analysis

ZeissToSGI
ZeissToSGI converts from a Zeiss AxioVision TIFF file to one that can be read by the SoftWoRx software on SGI machines. [Windows]
