进行很low的数据分析是一种什么体验?

分析某植物群体的分子数据, 想做一个高端大气的聚类树图,但使用的msap软件包只能绘制480*480像素的小图,样本一多,就特别难看,软件包没有直接提供可以调整的相关参数设置,而自己对R语言研究及其有限,于是我给软件的开发者发了一封邮件:
I want to use  msap  for drawing neighbor-Joining tree.  It could only create picture with 480*480 pixels,  it looks well with less than 30 samples. But I have about 90 samples , and I need creat a bigger picture. I don't know how to adjust the parameters.
很快收到了回信,给了一个链接,并说:
Anyway, take in mind that you can store the distance matrix and use it externally to plot different and improved trees (NJ tree in msap was intended as a raw exploratory analysis with very limited usefulness in most of the cases).
然后链接里解决方案的开头是这样写的:
The NJ plot form msap is awful, specially when the number of samples is big (>10). It was not intended to be very exahaustive, just as an exploratory analysis, but people seems to want to show it.

没错,我就是这个“people”,解决方案里的代码就是为我写,还是挺尴尬的,挺感动的。
这大牛可能搞不懂我这样的菜鸟为什么会有这么奇怪的需求, 这么low的需求,可我也明明看到有好几篇文献直接用了这个软件生成的NJ图,那几篇文章的水平还是挺不错。

菜鸟进阶之路不容易,一定要厚脸皮,相信以后如此low的叨扰会越来越少


后记:解决了这个问题后。我居然又发现了问题,折腾了半天,发邮件询问,结果是我多输入一对引号而导致报错。囧囧囧。“Let me know if you have further problems/questions”,真是一个好的师者。
