Removal of surname search from group projects page - retore it please

[wkauffman]

The search box that was on the group projects page has disappeared. https://www.familytreedna.com/projects.aspx One now has to click a section to find the search box. After the search you have to go back and select a group again because the search box is not retained on the search results page....

All testing goes back to the reference sequence. Ideally the testing firm would be able to access both presumed positive and negative samples to serve a validation controls. In these days theoretical estimates can replace physical lab testing during prototyping runs.

Testing for individual...

Haplogroup labels can also change when a new result splits an existing block of equivalent SNPs.

Coverage statistics of various types of y-tests can been found at https://haplogroup-r.org/stats.html Compare the Y500 numbers to the Y700 to see how much better it is. Note that the Y700...

Several items...
1) FTDNA has had problems reporting "no-calls" and filtering them out of results. If you see Reference = Genotype it is a bad call and should be ignored. You need to open the BAM files from both results and check the quality of any SNP results being compared. ...

SNP packs can test 150 SNPs at a time. Some are higher most are lower than 150. The backbone SNP pack provides a feeder into other 2nd level SNP packs within the R1b region. Your real cost now becomes at least 2 SNP packs. Those SNP packs were created based upon results from 1-5 years ago. Due to...

Age estimation will be affected by how FTDNA curates SNPs into shared haplogroup blocks and what they list as unshared in your sample. While it is hoped that they provide a method that is comparable to YFull or McDonald/Ytree other factors come into play. Known ancient samples provide carbon dated...

You really don't seem to get it when it comes to the RELEVANCE of the matches being presented. When counting to 30 you count for BOTH individuals not just the one back to a haplogroup level!!! So 23+xxx >30 and you won't see them. The current limit takes us back to about 2000 years ago. That...

There are other reasons for a lack of relevant matches at higher marker levels. They can include:
A) Your line resides on a rare or under-tested haplogroup branch. American, British Isle, and Scandinavian results dominate the system. All of continental Europe is under-represented and correspondingly...

FTDNA does not know about family relationships between test results. Each test result is based off of the information present on that account. Within a project an admin would group related results together and then individuals would be able to take the most refined haplogroup and apply it to all...

[wkauffman]

Correct. Based upon some of your STR marker values and the haplogroups of your matches one can get placed farther down the haplogroup under R-M269. This in turn can provide you guidance as to which potential tests would address your interests, research needs, and budget. Join the R1b gateway project...

Polluting the database with low resolution results




Now if FTDNA supported the file format and the data it contains FTDNA would have allowed the import of the original data file. You have uploaded data from the new series of chips that FTDNA does not support. ...

The called results could be different from what was expected due to quality, and corresponding coverage, differences between the initial samples. Looking at the the VCF files should show whether there was a significant difference in the quality of the calls. Viewing the BAM files won't provide much...

The quoted mutation rate is ONLY for the region that YFull does their analysis off of. They work off of a subset of the y to have consistent results from current sequencing technologies. Look at the math described in some of the R-U106 age analysis efforts under http://www.jb.man.ac.uk/~mcdonald/...

You reside on a haplogroup branch that is a) under tested, and/or b) is numerically rare in the overall population. As we get more test results in we are finding more of these "old" rare haplogroup branches. Patience is the key word for individuals in this situation as you are waiting on...

Place data into the public domain

The problem with most of the projects and data within the community is that individuals have not expressly consented and placed their results into the public domain. For projects with European members and data GDPR directly touches the information present...
