Map SNPs to UCSC latest freeze
* entries are required
BLAT created by Jim Kent, 2002 is used
1. *Please copy & paste in the SNPs data in proper format:
or upload data file
2. Please select the chromosome the SNPs are mapping to:
* Chromosome 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 X Y of latest version of UCSC freeze (be sure to select the correct one)
3. Adjustable parameters.
Use Fast Mode Medium Mode Slow Mode to map SNPs
Additional parameters for BLAT-based annotation:
Additional parameters for BLAST-based annotation:
For annotation,
First filter
@ Minimum size of match for valid hits bp for full range of normal SNPs; bp for each ends of insertion/deletions, (If your SNP is with shorter flanking sequences, please decrease this number accordingly) @ Minimum percentage of identities for valid hits 95% 96% 97% 98% 99% 100% @ The maximum length difference between query SNP and matching fragment is bp
@ Minimum size of match for valid hits bp for full range of normal SNPs; bp for each ends of insertion/deletions, (If your SNP is with shorter flanking sequences, please decrease this number accordingly)
@ Minimum percentage of identities for valid hits 95% 96% 97% 98% 99% 100%
@ The maximum length difference between query SNP and matching fragment is bp
Second filter
@ Only the best matches will be used for annotation All hits above filter will be used for annotation
4. Choice of outputs:
Show BLAST/BLAT annotation evidence of match identity percentage in Genbank annotation and features table
Annotation Genbank format data or Genbank format features (gbheader)
viewable in Vector NTI or Artemis
Feature table ready for database in tab-delimited format
Features failed to be annotated
Duplicated features (possibly false positive due to homologs)
Original BLAST/BLAT output
Data for the "custom track" of Genome Browser Name the track as
Annotation evidence (compact parsed BLAST/BLAT data)
Original full-length Genbank format data (with sequence body)
Original gbheader
