| If you have any general questions about snps this is a good resource: http://www.ncbi.nlm.nih.gov/bookshelf/br.fcgi?book=helpsnpfaq. In addition to the SNP-specific checks on this page, be sure to follow the [[New_track_checklist | new track checklist]], too.
| | This page is no longer maintained. |
| | |
| * look at mysql tables
| |
| ** check that the number of exceptions listed in snp###Exceptions and snp###ExceptionDesc match
| |
| ** make sure that there are no exceptions in the snp###Exceptions that do not also exist in the snp###ExceptionDesc table
| |
| ** If possible, compare to old SNP tables for this species. Look for big jumps in the number of different func types of SNPs as well as the number and type of exceptions.
| |
| ** check that func types in snp### table are documented in the html, both in the methods and in the check boxes. If there are new func types, make sure they are displayed correctly in the browser
| |
| ** check that the weights column in snp### are only 1,2 or 3
| |
| ** look the names of the snps. Make sure that they make sense (no extraneous ones, all lower case, etc). The checkHgFindSpec tool with the -checkTermRegex option will check that all of the names in the snp### table match the regular expression specified in trackDb. There is not an option to run it on a single table, so just run it on the whole database and look for output specific to the snp table. For instance:
| |
| | |
| checkHgFindSpec -checkTermRegex hg19
| |
| | |
| * check settings (hgTrackUi and clicking on individual snp)
| |
| ** make sure that all settings that you can select for are present in mysql tables and vice versa
| |
| ** make sure that methods mention all func types that you can select in trackUi
| |
| ** check that can turn different gene tracks on in the trackUi
| |
| | |
| ** look at featureBits/Coverage for main snp table as well as the dbCoding and the ortho table. Also check coverage of haplo chromosomes.
| |
| ** see how coverage compares to old snp track if possible. Also when open up the track, most snps should match to the same place (though some will change)
| |
| | |
| ** make sure appropriate entries in hgFindSpec (this is very important for snps since the table is so large). Check that entries in hgFindSpec work by searching for some snps.
| |
| ** make sure track "turns off" when viewing large regions (table too large to load for large regions)
| |
| ** look at large snp insertions/deletions and check that display correctly in hgTracks and hgTrackUi
| |
| | |
| * description
| |
| ** make sure external files mentioned at the end of the html page exist at ncbi
| |
| | |
| * default position - is it turned on by default?
| |
| | |
| * if this is a human assembly, make sure there are downloads for "Masked FASTA Files (human assemblies only)"
| |
| | |
| ==AT RELEASE BE SURE TO:==
| |
| # push tableDescriptions and hgFindSpec
| |
| # edit trackDb.ra so that old snp track is hidden by default if needed
| |
| # make announcement on genome announce
| |
| # notify Mark D so he can update LS-SNP
| |
| # notify Galt so he can default to most current snp track in genome graphs
