我最近收到了一个由 Roche LightCycler 480 仪器生成的示例导出文件。它使用专有的 XML 格式，对此我还没有找到规范。
从这些类型的文件中，我想提取一些与我的目的相关的信息。尽管其中大部分都可以轻松解析和解释，但它包含许多(未填充的)base 64 编码的二进制/序列化数据字段，表示整数和/或浮点数数组。示例文件的链接可以在 this gist 中找到。 .
我在这篇文章的末尾包含了它的一些片段。 AcquisitionTable共包含19此类编码 item条目。这可能代表整数( SampleNo )和浮点( Fluor1 )值的数组。
我仍然不清楚如何将解码的字节转换为整数或浮点值。当 base 64 解码时，每个项目都以以下(十六进制)6 字节序列开头:
42 41 52 5A 00 00 ... // ['B','A','R','Z','\0','\0', ...]
请注意，虽然我期望每个“项目”包含相同数量的数字(或此表中的“行”)，但我观察到类似项目的解码字节数不同:5654 表示
Fluor1和 5530 为 Fluor2 .此外，对于那些我怀疑包含(顺序)整数的数组，可以观察到一个模式:
SampleNo : ... 1F F5 1F 07 2F 19 2F 2B 2F 3D 2F 4F 2F 61 2F 00 73 2F 85 2F 97 2F A9 2F BB 2F CD 2F DF 2F F1 2F 00 03 3F 15 3F 27 ...
Cycles : ... 1F FF 1F 11 2F 23 2F 35 2F 47 2F 59 2F 6B 2F 00 7D 2F 8F 2F A1 2F B3 2F C5 2F D7 2F E9 2F FB 2F 00 0D 3F 1F 3F 31 ...
Gain : ... 1F EE 1F 00 2F 12 2F 24 2F 36 2F 00 48 2F 5A 2F 6C 2F 7E 2F 90 2F A2 2F B4 2F C6 2F 00 D8 2F EA 2F FC 2F 0E 3F 20 3F 32 ...
它看起来像字节对，其中第二个字节增加了
0x12 (18) 偶尔还有一组 3 个字节，带有 0x00作为第二个字节，以防最后一个字节的半字节是 3 , D或 8分别为三个例子。我想知道编码/序列化格式的类型是否对任何人都是显而易见的(或者，如果有人有这种文件格式的规范，那就更好了)。
我相信用于创建这些文件的软件目前是基于 Java 的，但作为 Windows/MFC/C++ 产品的历史。

最佳答案
这就是我到目前为止所拥有的。
根据可读数据推断，您使用的文档并非来自实际的 PCR 运行。这是一个颜色补偿运行 ( short overview that seems to match the file ) ( full updated manual, page 250, not as fitting )。具体来说，它似乎是“FAM/Pulsar 650”染料的颜色补偿运行。
正如您所指出的，输出类型是具有 2400 个“计数”的“采集表”，我相信它必须与您通常从 PCR 运行中获得的输出不同。我相信您已经找到了这些，但是一些公开的 PCR 模板示例(未完成的运行)是 here , here , here和 here .
根据您文件中的 LCRunProgram，这里的协议(protocol)是:
以 20°C/s 的速度保持 95°C 0"
保持 40°C 30"，20°C/s
以 0.1°C/s 的速度保持 95°C 0"，采集模式“2”。
因此，我们预计采集时间范围持续估计 (95°C-40°C)/0.1°C/s = 550 秒，大约；在此期间，每秒应该有固定数量的采集事件。
EDIT 0 - 这是我在开始时所做的，所以我没有删除它，但后来我得到了更多有趣的信息(见下文)。
我用一个简单的 Python 脚本(我是 Python 专家)查看了数据，以搜索模式。该脚本将数据的初始字符串保存在名为 values 的字典中。在这里发布太长了；所以here's it in a gist ，就像你必须做的那样。

让我们避开显而易见的事情，说
ProgramNo和 CycleNo持有相同的数据；和所有 Gain是相同的。所以我只发一张。现在尝试使用分隔符
b'\r' 的脚本(只是尝试一个)将其中的一些切成 272(271+个分隔符)字节的块。其他的不整洁。separating by: b'\r'
SampleNo [1536; 1152] separated in 5 chunks: [174, 271, 271, 271, 161]
ProgramNo [1531; 1148] separated in 6 chunks: [47, 271, 271, 271, 271, 12]
SegmentNo [1531; 1148] separated in 5 chunks: [169, 271, 271, 271, 162]
通过
b'\t' 分隔给出类似的结果:separating by: b'\t'
SampleNo [1536; 1152] separated in 5 chunks: [204, 271, 271, 271, 131]
ProgramNo [1531; 1148] separated in 5 chunks: [76, 271, 271, 271, 255]
SegmentNo [1531; 1148] separated in 5 chunks: [199, 271, 271, 271, 132]
并由
b'\n' 分隔以类似的方式分割这次的 yield :separating by: b'\n'
Gain1 [3046; 2284] separated in 10 chunks: [81, 271, 271, 271, 271, 271, 271, 271, 271, 26]
所以我并不是在暗示这些“分隔符”有任何重要性；我认为它们是罕见的字符，它们似乎将数据切成 272 字节的块，而这个 272 字节的值对于理解这些数据的存储方式可能很重要。
每个字符串“BARZ”的开头似乎是一个“foo-bar”的东西；可能在标题的开头设置为检查。
另一件有趣的事情是
gains数据分成 8 个相同大小的块(加上其他两个较小的块)。如果此数据来自 96 孔板，我将开始探索这是否可能是一个标题，然后是 8 个可拆分为 12 个项目(列)的块(行)，以便 8*12=96 复制设置96 孔板。此外，如果这个“每行 272 字节”假设成立，那么
ProgramNo 中的数据, SampleNo如果板未装满，则可以解释确实分成 272 字节块的等，并且一些孔有 sample (有几条完整的线)而其他孔是空的。我不确定这对于色彩补偿板是否有意义。Time , Temperature , Error和 Fluor s 不分成块，您认为它们是一组连续值是正确的；虽然不一定 float 。荧光可以被捕获为可能是正整数的“单位”(我没有 LightCycler 所以我不知道是否是这种情况)。这就是我目前所处的位置。我不确定我是否有时间走得更远。如果我没有回复，祝你的努力好运。

所以关于
SampleNo数据，它似乎是这样构造的:1) 一个 header ，可能会或可能不会被 0x00 分隔，例如:
*
BARZ header ，然后是 2 次 0x00(共 6 个字节)* 三个字节，然后是 0x00(共 4 个字节)
* 17 个字节，然后是 0x00(共 18 个字节)
2) 一系列数据，每个数据由 16 个字节组成并以 0x00 终止(因此每个数据为 17 个字节)。
这意味着
Samples包含一个头部，加上 66 组 17 字节。编辑2:
使用这段糟糕的代码将所有内容按 0x00 拆分:
def splitme(name):
data = base64.b64decode(values[name]+'==')
hit = 0
index = 0
countit = 0
splits = []
while hit >= 0 and countit < 500:
countit += 1
hit = data[index+1:].find(0)
index += hit+1
if hit >= 0:
splits.append(index)
lastindex = -1
splitted = []
if splits:
for index in splits:
splitted.append(data[lastindex+1:index])
lastindex = index
else:
splitted = [data]
产量:

所以
SampleNo , ProgramNo , SegmentNo , Error和 Gain s 全部拆分为 17 个字节的块(16 个字节 + 0x00)。编辑 3:
ProgramNo 的前十五个 17 位块(以及副本 CycleNo )和 Error是相同的。只是为了澄清，我描述的“块”是您所描述的一系列数字对，其中一个增加了 0x12。您提到的 0x00 是块之间的分隔符。
编辑 4:
关于
Gain数据，我最初的“272 字节”块和 (16+0x00) 字节块之间的链接，是有 16 个块的重复模式，其中 15 个是“16+0x00”块，最后一个块有 0x00在中间。所以 17 字节(=16+0x00)* 16 个块 = 272 字节的总重复。整个字符串的构建如下:“标题”部分，然后是 8 个 17bytes*16 块的重复，最后是 4 个 17bytes 块。因此，一方面我对 8 个块是正确的，但显然我在与 8x12 孔 PCR 板平行时错了。这里更像是 8*16 (+4)。
关于
Fluor等数据，我没有答案，但我会尝试剥离标题，看看是否有任何(整数或浮点数)压缩算法可以处理它......压缩数据将解释为什么这些字段的长度不同.
