Local Ancestry in adMixed Populations
Registration Form and License Agreement

LAMP-LD is a software package for the inference of locus-specific ancestry in recently admixed populations.

LAMP-LD takes the genotypes of admixed individuals as well as reference haplotype panels approximating the mixing ancestral populations, and outputs the estimated number of alleles from each ancestry in each locus for each individual.

The LAMP-LD package also includes the program LAMP-HAP, which processes haplotype data when high-quality phasing is available, and utilizes trio nuclear family designs to improve estimation accuracy.

LAMP-LD is based on a window-based processing combined within a hierarchical Hidden Markov Model. It can process 2,3, or 5 mixing populations, and its short per-sample processing time makes it suitable for analyzing large datasets of dense SNP panels.

License Agreement:

The computer software known as LAMP-LD (`LAMP' or `The Software') was created and developed in the course of research by Dr. Yael Baran, Dr. Sriram Sankararaman, Dr. Bogdan Pasaniuc, and Dr. Eran Halperin (`The Researchers') at Tel-Aviv University ('TAU') and the International Computer Science Institute, Berkeley (`ICSI'). ICSI and TAU encourage the use of LAMP by researchers in academic institutions (`Licensee') for non-commercial research purposes subject to the following terms and conditions: By pressing the `Agreed and Accepted' button, you and your institution agree to be bound by the terms below.

  1. Licensee is hereby granted a non-exclusive, non-transferable license to use LAMP for the sole purpose of performing non-commercial academic research. Such research shall not include research sponsored by a commercial entity.
  2. For the avoidance of doubt it is hereby clarified that the license to use LAMP as aforesaid does not include any obligation or undertaking to supply any accompanying services or improvements.
  3. Licensee agrees not to distribute or transfer LAMP or any portion, copies or derivatives thereof, to another location or to any third party.
  4. Licensee agrees not to make any copies except as necessary for his exercise of this license in his own laboratory. Any copy shall bear an appropriate copyright notice specifying the above-mentioned authors and proprietor.
  5. Licensee agrees not to decompile, reverse engineer, disassemble, modify and /or create derivative works of the software.
  6. Licensee acknowledges that LAMP is a research tool, still in the development stage. Hence, it is not presented as error free, accurate, complete, useful, suitable for any specific application or free from any infringement of any rights. The Software is licensed AS IS, entirely at the Licensee's own risk.
  7. Nothing in this Agreement shall be deemed to be a warranty or representation by TAU, ICSI or the Researchers, in connection with LAMP and its use, including, without limiting the generality of the aforesaid, as to the accuracy, safety or fitness for any particular use.
  8. The software is provided "as is", without warranty of any kind, express or implied, including but not limited to the warranties of merchantability, accuracy, fitness for a particular purpose and noninfringement. In no event shall the authors or copyright holders of LAMP (including TAU, ICSI and the researchers) be liable for any claim, damages or other liability, whether in an action of contract, tort or otherwise, arising from, out of or in connection with the software or the use or other dealings in the software.
