Explanation: Why the Primer is at the “End” of the Transposon Sequence
Explanation: Why the Primer is at the “End” of the Transposon Sequence
This is an excellent and important question about the library preparation strategy. Let me clarify the apparent contradiction.
Short Answer
The primer AGCTTCAGGGTTGAGATGTGTATAAGAGACAG is positioned at the transposon-genome junction — but “end” depends on directionality and sequencing orientation. When we write the transposon sequence 5’→3′, the primer-binding region appears at the 3′ end because that’s the end that abuts the genomic DNA after insertion. Sequencing proceeds from the primer INTO the genome, not the other way around.
Detailed Explanation
1. Transposon Structure and Orientation
The Tn5 transposon has two key features at each end:
[Genomic DNA] ← insertion site → [Transposon End (ME sequence)] ← [Primer Binding Site] → [Rest of Transposon/Adapter]The sequence you see in the PDF is written 5’→3′ in the orientation of the transposon construct:
5'-[Long transposon body]...[ME recognition sequence: AGATGTGTATAAGAGACAG]-3'
↑
Primer binds here
Sequencing proceeds → INTO genomic DNA2. The Mosaic End (ME) Sequence
From your PDF:
ME Erkennungs Sequenz 5´ AGATGTGTATAAGAGACAG 3´
ME Sequenz Komplementär: 3´ TCTACACATATTCTCTGTC 5´
ME Sequenz Rev Komplementär: 5´ CTGTCTCTTATACACATCT 3´The primer you use (AGCTTCAGGGTTGAGATGTGTATAAGAGACAG) contains: |
Component | Sequence | Function |
|---|---|---|---|
| Additional 5′ extension | AGCTTCAGGGTTGAG |
Provides binding stability, may contain adapter/index sequences | |
| Core ME recognition | ATGTGTATAAGAGACAG |
Essential for Tn5 transposase binding and insertion |
3. Why the Primer Must Be at the “End”
A. Sequencing Directionality
Illumina sequencing reads 5'→3' from the primer:
Primer: 5'-AGCTTCAGGGTTGAGATGTGTATAAGAGACAG-3'
↓
Sequencing extends → → →
↓
[Genomic DNA insertion site]If the primer were at the “beginning” of the transposon sequence, sequencing would read through the transposon body instead of into the genome — yielding no useful insertion site information.
B. Library Preparation Workflow
1. Tn5 transposon inserts into genomic DNA at random TA sites
2. Genomic DNA is fragmented around insertion sites
3. PCR amplification uses primers binding to transposon ends
4. Sequencing read 1 (R1) starts at transposon primer → reads INTO genome
5. Sequencing read 2 (R2) may capture barcode + opposite genomic flankC. The “Staggered” Primer Start (Cycles 5-10)
Your pipeline searches for the primer starting between cycles 5-10 because:
Primer variants used (from PDF):
NEB_i5_Tn_01: 5'-ACACTCTTTCCCTACACGACGCTCTTCCGATCTACCTACAACAAAGCTCTCATCAACC-3'
NEB_i5_Tn_02: 5'-ACACTCTTTCCCTACACGACGCTCTTCCGATCTCACCTACAACAAAGCTCTCATCAAC-3'
NEB_i5_Tn_03: 5'-ACACTCTTTCCCTACACGACGCTCTTCCGATCTCCTACAACAAAGCTCTCATCAACCG-3'
These primers have variable 5' overhangs (frameshifts) to:
- Create diversity at the start of Read 1 (improves cluster identification on Illumina flow cells)
- Ensure the core ME sequence (`AGATGTGTATAAGAGACAG`) is still recognized by the pipeline4. Visual Summary: Read Structure After Insertion
Genomic DNA (unknown) ← [Insertion Site: TA] ← [Transposon ME End] ← [Primer Binding Site]
Sequencing Read 1 (R1):
5'-[Primer: AGCTTCAGGGTTGAGATGTGTATAAGAGACAG][Genomic DNA...]-3'
↑ ↑
Primer binding site Genomic sequence starts here
(searched for in pipeline) (extracted and mapped to genome)
Pipeline step:
1. Identify primer pattern in R1 (allowing 1 mismatch, start position 5-10)
2. Extract suffix AFTER primer = genomic DNA
3. Map genomic suffix to reference genome
4. Record insertion coordinate = position immediately after TA dinucleotide5. Why This Design Works for Tn-Seq
| Design Feature | Purpose |
|---|---|
| Primer at transposon-genome junction | Enables sequencing FROM known transposon INTO unknown genome |
| ME sequence within primer | Ensures only true transposon insertions are captured |
| Variable start position (cycles 5-10) | Improves Illumina cluster diversity; accommodates library prep variants |
| Genomic suffix extraction | Isolates the biologically relevant insertion site for mapping |
Key Takeaway
The primer appears at the “end” of the written transposon sequence because that end is physically adjacent to the genomic DNA after insertion. Sequencing proceeds from this primer into the genome, allowing us to identify exactly where the transposon inserted. If the primer were at the opposite end, we would sequence through the transposon body and miss the critical genomic insertion site.
This orientation is fundamental to all Tn-seq, Tn5-seq, and similar insertion sequencing methods — the primer must be positioned to read from the known transposon sequence into the unknown genomic context.

Explanation of Start-Position 5-10
What Does “Start-Position 5-10” Mean?
The start-position 5-10 refers to the cycle number (nucleotide position) in Read 1 where the transposon primer sequence begins. This is intentional diversity created during library preparation.
Why Positions 5-10?
Looking at your PDF, three different forward primers are used:
NEB_i5_Tn_01: 5'-ACACTCTTTCCCTACACGACGCTCTTCCGATCT**ACC**TACAACAAAGCTCTCATCAACC-3'
NEB_i5_Tn_02: 5'-ACACTCTTTCCCTACACGACGCTCTTCCGATCT**CAC**TACAACAAAGCTCTCATCAAC-3'
NEB_i5_Tn_03: 5'-ACACTCTTTCCCTACACGACGCTCTTCCGATCT**CCT**ACAACAAAGCTCTCATCAACCG-3'
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Constant Illumina adapter (33 bp)Key insight: The primers have:
- Constant region (first 33 bp):
ACACTCTTTCCCTACACGACGCTCTTCCGATCT(Illumina adapter) - Variable frameshift (2-3 bp):
ACC,CAC, orCCT - Transposon amplification sequence:
TACAACAAAGCTCTCATCAACC...
This creates a frameshift so the transposon sequence starts at different positions (cycles 5-10) in the sequencing read, improving cluster diversity on Illumina flow cells.
How to Implement Start-Position 5-10 in Code
In TPP (Transposon Position Profiling)
The pipeline uses the -primer-start-window parameter:
# Example from your pipeline:
python3 ~/.local/bin/tpp -bwa /usr/bin/bwa \
-protocol Tn5 \
-ref CP009367.fasta \
-reads1 sample_R1.fastq.gz \
-reads2 sample_R2.fastq.gz \
-output sample_run3 \
-primer AGCTTCAGGGTTGAGATGTGTATAAGAGACAG \
-mismatches 1 \
-bwa-alg mem
# -primer-start-window is set internally to allow positions 5-10Modifying the TPP Script
From your pipeline notes:
# Modify the TPP tools to set the correct window
vim ~/.local/lib/python3.10/site-packages/pytpp/tpp_tools.py
# Search for "DEBUG" or "primer-start-window"
# The default is set to: -primer-start-window 0,159
# But for your case, you want to restrict to positions 5-10Implementation Logic
The code should:
- Search for primer in Read 1
- Check start position – must be between cycles 5-10 (0-indexed: positions 4-9)
- Allow 1 mismatch in the primer sequence
- Extract genomic DNA after the primer
Pseudocode example:
def find_transposon_primer(read_sequence, primer="AGCTTCAGGGTTGAGATGTGTATAAGAGACAG",
max_mismatches=1, start_window=(4, 9)):
"""
Find transposon primer in read with position constraint.
Args:
read_sequence: The R1 read sequence
primer: Transposon primer sequence
max_mismatches: Maximum allowed mismatches (default: 1)
start_window: Tuple of (min_pos, max_pos) for primer start (0-indexed)
Returns:
genomic_sequence: Sequence after primer if found, else None
"""
primer_len = len(primer)
# Search in the allowed window (positions 5-10 in 1-indexed = 4-9 in 0-indexed)
for start_pos in range(start_window[0], start_window[1] + 1):
end_pos = start_pos + primer_len
if end_pos > len(read_sequence):
continue
# Extract candidate sequence
candidate = read_sequence[start_pos:end_pos]
# Count mismatches
mismatches = sum(1 for a, b in zip(candidate, primer) if a != b)
if mismatches <= max_mismatches:
# Found valid primer! Extract genomic sequence
genomic_sequence = read_sequence[end_pos:]
return genomic_sequence, start_pos
return None, None # Primer not found in valid positionActual TPP Parameter
Looking at your pipeline, the modification shows:
# In tpp_tools.py, there should be a parameter like:
-primer-start-window 0,159 # Default allows positions 0-159
# But for your specific case with frameshift primers,
# the effective positions are 5-10 due to the primer designWhy Window is 0-159 but Effective is 5-10?
The 0-159 window is a permissive search range to find the primer anywhere in the read. However, due to your primer design (33 bp adapter + 2-3 bp frameshift), the transposon sequence naturally starts at positions 5-10.
Read structure:
Position: 1-33 34-35/36/37 36/37/38 onwards
[Illumina] [Frameshift] [Transposon + Genomic]
Adapter ACC/CAC/CCT AGCTTCAGGGTTGAG...
After sequencing from the other end:
Position: 1-4 5-10 11+
[Random] [Transposon] [Genomic DNA]Verification in Your Data
From your pipeline output:
# Break-down of total reads (49821406):
# 29481783 reads (59.2%) lack the expected Tn prefix
# Break-down of trimmed reads with valid Tn prefix (20339623):This shows that ~40% of reads have the transposon primer starting in the valid window (positions 5-10), which is expected given the library design.
Summary
- Start-position 5-10: The transposon primer starts at cycle 5, 6, 7, 8, 9, or 10 in Read 1
- Purpose: Created by mixing 3 primers with frameshifts to improve Illumina cluster diversity
- Implementation: TPP searches for primer with
-primer-start-windowparameter (default 0-159, but effective range is 5-10 due to primer design) - Code: Search for primer sequence allowing 1 mismatch, verify start position is in range, extract genomic suffix

Leistungsklassen（级别组/实力组）详细说明
📋 基本概念
Leistungsklassen 是德国国际象棋比赛中的按棋力水平划分的组别，与按年龄划分的 Altersklassen（年龄组） 不同。
🔍 核心区别
| 分类方式 | 德文 | 中文 | 划分依据 |
|---|---|---|---|
| 级别组 | Leistungsklassen | 实力组/级别组 | 棋手水平（DWZ等级分） |
| 年龄组 | Altersklassen | 年龄组 | 年龄（U8/U10/U12…） |
🏆 汉堡青年象棋的 Leistungsklassen 体系
根据您上传的 HJET 2026 文件，汉堡青年象棋联盟（HSJB）设有以下级别组：
级别组 I（Leistungsklasse I）
- 最高水平组
- 参赛者：强手、有丰富比赛经验的棋手
- 使用国际象棋钟（Schachuhr）
- 必须记录棋步（Züge mitschreiben）
- 比赛成绩计入 DWZ（德国棋手等级分）
级别组 II（Leistungsklasse II）
- 中级水平组
- 参赛者：有一定比赛经验，但尚未达到顶级水平的棋手
- 同样使用棋钟和记录棋步
- 成绩也计入 DWZ
年龄组（Altersklassen）
- 初学者组
- 参赛者：新手或很少参加比赛的棋手
- 通常不使用棋钟（或仅在必要时）
- 不强制记录棋步
- 不计入 DWZ
📊 升降级制度（Auf- und Abstieg）
根据 2026 年规则：
从级别组 I 降级
- 最后 6 名 → 降至级别组 II
从级别组 II 升级
- 第 1-6 名 → 升至级别组 I
- 最后 6 名 → 降至年龄组
从年龄组升级
- U14-U18 各年龄组冠军 → 升至级别组 II
🎯 参加汉堡锦标赛（HJEM）的资格
重要区别：
| 组别类型 | HJEM 资格 |
|---|---|
| 级别组 I & II | ✅ 所有参赛者自动获得资格（无需通过 HJET 选拔） |
| 年龄组 | ⚠️ 必须通过 HJET 达到规定名次才能获得资格 |
💡 这就是为什么文件说：”虽然所有级别组的参赛选手通常均可参加汉堡锦标赛，但年龄组中仅部分选手能够成功获得资格。”
📈 DWZ（德国棋手等级分）系统
DWZ（Deutsche Wertungszahl） 是德国国际象棋协会（DSB）的官方等级分系统：
| DWZ 分数 | 水平描述 |
|---|---|
| < 1000 | 初学者 |
| 1000-1300 | 业余棋手 |
| 1300-1600 | 俱乐部中坚力量 |
| 1600-1900 | 强业余棋手 |
| 1900-2200 | 专家级 |
| > 2200 | 大师级 |
🎓 实际意义
为什么设置 Leistungsklassen？
-
公平竞争
让水平相近的棋手互相对弈，避免新手被强手碾压 -
激励机制
通过升降级制度，鼓励棋手不断提升 -
选拔功能
级别组选手直接获得锦标赛资格，确保高水平选手参赛 -
循序渐进
新手从年龄组开始，逐步晋级到级别组 II，再到级别组 I
📝 举例说明
假设有一个 10 岁棋手：
| 情况 | 参赛组别 | HJEM 资格 |
|---|---|---|
| DWZ 1500，经常参加比赛 | Leistungsklasse II | ✅ 自动获得 |
| DWZ 1200，偶尔参加比赛 | Leistungsklasse II 或 U10-1 | 取决于选择 |
| 刚学棋，无 DWZ | U10-2（年龄组） | ⚠️ 需在 HJET 前 16 名 |
✅ 总结
Leistungsklassen 是德国象棋体系中：
- 按棋力而非年龄分组
- 有明确的升降级机制
- 提供直接锦标赛资格
- 使用 DWZ 等级分作为参考标准
这种制度确保了比赛的公平性和竞技性，同时为不同水平的棋手提供了合适的参赛平台。

🏆 汉堡国际象棋锦标赛资格赛说明
一般规定：
汉堡青年国际象棋单项赛 (HJET) 是汉堡国际象棋锦标赛的资格选拔赛。虽然所有级别组 (Leistungsklassen) 的参赛选手通常均可参加汉堡锦标赛（详见《比赛规程》第4条），但年龄组 (HJET U8 – U18) 中仅部分选手能够成功获得资格。
针对 2026年汉堡锦标赛，教学委员会 (Lehrausschuss) 决定：在 HJET 开赛前，部分确定提名规则。所有年龄组参赛选手，若在 HJET 中达到以下名次，将获得汉堡锦标赛的参赛邀请。因此，在赛事开始前即可明确：年龄组中哪些 HJET 比赛成绩足以获得资格。
⚠️ 重要提示：即使名次低于下述标准的选手，也可能已通过其他途径获得汉堡锦标赛资格！教学委员会将在 HJET 结束后，再决定其余参赛邀请名额。
对于 U12 及以上年龄组、但未获得 HJEM 资格的儿童和青少年，可报名参加 Schönhagen-Cup（名额有限）。

Comparing intra- and inter-host variants (40 positions are common between spandx and vphaser2)
Please find attached the complete variant calling results for our 229E passaging experiment (2024–2026 datasets): variant_annot_2026__final.xls. • Sheet 1 (All_SNPs_Indels_annotated): Inter-host variants called by spandx. Shows consensus alleles at each variant position across all 10 samples relative to the PP810610 reference. • Sheet 2 (isnvs_annot): Intra-host variants called by vphaser2. Provides precise allele frequencies (iSNV_freq) per sample to quantify within-host diversity. Overlap: Green-highlighted rows indicate variants consistently detected by both pipelines. Sheet 2 is a subset of Sheet 1, focusing only on positions with intra-host heterogeneity. Fixed differences from the reference (where all 10 isolates share the same non-reference allele) remain in Sheet 1 (white rows). A few positions in Sheet 2 show iSNV_freq ≈ 1.0 (e.g., POS 15458, 22636).
