This page is designed to be used for single or multiple text based searches of the Human Transcript Database.
A single parameter search may be performed by selecting the field to be searched from the pull-down list, entering a parameter in the box directly under the first field box and clicking t he 'Submit' button at the bottom of the form(note: searches are not case sensitive).
Multiple parameter searches may be perfomred by selecting search parameters from the second and third fields in addition to the first field. Searches may be narrowed by selecting 'And' or broadened by selecting 'Or'. The third field box contains numberic fields that can be searched for a range of values, these include transcript size and date of entry amoungs others. Transcript length should be entered in bases, Sequence characteristics as a number between 0-4, and date of submission as follows YYYY/MM/DD (e.g. for Dec 15, 1998 you would enter 1998/12/15). The wildcard '*' may be used for searching in the first or second fields and it may appear at an y location in the parameter. The results from a query may be sorted by one of several different fields. Lastly, the search can be limited to only the cDNAs sequenced at the Baylor College of Medicine Human Genome Sequencing Center by checking the box at the Bottom of the form.
Example 1: to search for cDNA sequences submitted to GenBank by Gibbs
1) Select 'Author' from the first field.
2) Enter 'Gibbs' in the search parameter directly under the first field
3) Click the SEARCH button
Example 2:
to search for cDNA from brain tissue that is between 100 and 1,000 bases long sorted by size
1) Select 'Tissue Type' from the first field
2) Enter 'brain' in the search parameter directly under the first field
3) Select 'Transcript Length' from the third field
4) Enter '100' in the top box next to the third field
5) Enter '1000' in the bottom box next to the third field
6) Select the 'AND' button just above the third field
7) Select 'Transcript Length' from the sort by box
8) Click the SEARCH button
Example 3: to select every cDNA sequence that has 'actin' in the keywords, in muscle tissue, submitted before 12 Feb 1996, and sorted by sequence characteristic
1) Select 'Keywords' in the first field.
2) Type 'actin' in the search parameter directly under the first field.
3) Select 'Tissue Type' from the second field
4) Type 'muscle' in the search parameter under the second field.
5) Select the 'AND' button just above the second field.
6) Select 'Date Submitted' from the third field.
7) Enter 1996/02/12 in the lower box next to the third field.
8) Select the 'AND' button just above the third field.
9) Select 'Sequence Characteristic' from the third field.
10) Click the SEARCH button.
