Search Examples

Substructure(default)

Search for substances which match the query.
Substitution is allowed at all open positions.
Additional components may be retrieved.

ClosedSubstructure

Search for substances which match the query
exactly. Substitution is allowed at positions byassigning non-hydrogen attachments. Right click on anode or group of nodes and use the Non-Hydrogen

The SELECT command is used to create E-numbers containing terms taken from the specified field in ananswer set.
The ANALYZE command is used to create an L-number containing terms taken from the specified field in ananswer set.
The SORT command is used to rearrange the search results in either alphabetic or numeric order of thespecified field(s).

YCrossover from DWPIM to WPIX, WPIDS, or WPINDEXThe crossover from DWPIM results to WPIX, WPIDS or WPINDEX is established by performing a searchof the respective DWPIM L-number in WPIX, respectively WPIDS or WPINDEX.
There is a limit of 200,000 answers that can be crossed over from DWPIM to DWPI (WPINDEX, WPIDS,WPIX) in a single crossover L-number.
=> FIL DWPIM=> S L-number search type (e.g., L1 sss ful)=> FIL WPIX=> s L-number=> d L-number
The assembled display is the default display in WPIX. The commands for the assembled, brief and full
hit structure in WPIX are as follows:=> d L-number ahitstr=> d L-number bhitstr=> d L-number fhitstr

Crossover of Compounds from WPIX, WPIDS, or WPINDEX to DWPIM
Use the Transfer command to crossover Markush compound numbers from WPIX, WPIDS, or WPINDEX toAccession Numbers for Markush compounds in DWPIM. It is important to note that a reassignment of thecompound suffix MCN to AN is required.
The workflow is described in the following:
