 +=== New Features in NIST MS Search version 2.0g (May 2011 release) ===
 +
 +== What's New in the NIST MS Search Program v.2.0g ==
 +
 +<WRAP center round tip 85%>
 +  - Search for the **exact mass** value in the NIST/EPA/NIH Mass Spectral Databases or any User Database and use of the __accurate__ or __exact__ mass as a search constraint.
 +  - Search for __exact fragment ion mass__ values in NIST 11 Databases **mainlib**, **replib**, and **nist_msms**.
 +  - Display of the __exact mass__ with any spectrum that has an associated elemental composition (chemical formula).
 +  - Optional columns in Hit Lists containing the number of **Synonyms** and the number of Other Databases in which the Hit appears. The **Hit List** can be sorted according to the values in these columns.
 +  - Managing and searching as many as 127 separate mass spectral databases instead of 16, which was the limit in previous versions.
 +  - Up to 1,048,560 spectra in a single database instead of 786,420 spectra allowed in the previous versions.
 +  - Import spectra from mzXML and mzData MS and MS/MS files (in addition to mgf, msp, dta, pkl, JCAMP, etc.)
 +  - Option to turn off homolog hits in a **Structure Similarity Search**.
 +  - Full compatibility with most recent [[http://peptide.nist.gov/|NIST Peptide MS/MS Databases]].
 +  - Sorting the **Spec List** alphabetically and by the accession numbers.
 +  - Copying selected lines from **Hit List** or **Spec List** into Windows Clipboard as tab-delimited Unicode text; this may be conveniently pasted into Excel.
 +  - MS/MS Instrument Type constraint.
 +  - Tags in Comment constraint has been enhanced to include Tags in **Text Information** window.
 +  - When a Tagged item from the Comment is displayed separately in **Text Information** window its display in the __Comment__ line is suppressed.
 +  - Searching for a text in a **Text Information** window of a spectrum.
 +  - Spectra in the MSP text format can be imported from the Windows Clipboard into the **Spec List**.
 +  - Default view of Constraints and Other Searches dialog boxes changed to provide more convenience to the users.
 +  - An alternative peak matching method has been added to improve the reliability of the score when searching noisy MS/MS spectra.
 +  - The [[chemdata:interpreter|MS Interpreter Program]] displays high accuracy mass for both molecular ions and product ions and can use __exact mass__.
 +  - The ability to **Hot-Key** between tab displays of the Program using **Ctl-Tab** and **Ctrl-Shift-Tab** has been added.
