ioda for Pc

1. It is a scientific application that permits to read files at various formats as FITS used in astronomy, AIDA and ROOT used in high energy physics (HEP) to store histograms tuples and geometries, CSV to store tuples, DICOM used in medical, GDML to store detector geometries, DOT to describe graphs, JPG and PNG format to store images and FOG developed at CEA/Saclay (France) to describe the LHC/ATLAS geometry.

2. If the HDU is an IMAGE_HDU type, ioda attempts to visualize it as an image (which is one of the primary goal of the FITS format : store astronomical pictures).

3. It is available for a "flat TTree" in a ROOT file, a BINARY_TABLE in a fits file, a flat ntuple in an AIDA file and table data in a csv file.

4. ioda presents the list of the columns, the wanted projection (1D, 2D), proposes the histogram booking parameters and then does the projection and plots the histogram.

5. For ROOT files, ioda can plot TH[1,2][D,F] objects along than TProfile ones.

6. If the HDU is a BINARY_TBL, ioda shows a description of the columns (name, type) and proposes to histogram and plot a selected column.

7. ioda permits to browse these files and visualize some of their data.

8. Files at the FOG CEA/Saclay format permit to visualize LHC/ATLAS sub detectors.

9. For FITS astronomy files, the "HDUs" can be listed and their keys can be seen.

10. ioda can do "ntuple" projection in 1D or 2D histograms.

11. ioda should be read "IO-DA", for Input/Output and for Data Analysis.
