在Python中,当我们使用NumPy等库处理数组时,如果尝试访问超过数组实际维度的索引,就会引发“IndexError: too many indices for array”的错误。这个错误信息表明你为数组提供了两个索引,但数组只有一维。原因分析:这个错误通常发生在以下情况: 误以为多维数组实际上是一维的。 在处理数组时,索引的顺序或数量不正确。
In Python, the objects that implement the__getitem__method are calledsubscriptableobjects. For example, lists, dictionaries, tuples are allsubscriptableobjects. We can retrieve the items from these objects using Indexing. The TypeError: ‘NoneType’ object is not subscriptableerror is the most common...

The pattern was indexed with: Pattern centre: [PCx = 0.48, PCy = 0.28, DD = 0.64] Euler angles: [ϕ1 = 127°, Φ = 38°, ϕ2 = 273°] Detector tilt = 5° Sample tilt = 70°. This results in the following rotation matrices:Rzϕ1=−0.60180.79860−0.79860.60180001Rx...
Based on this concentration, the samples were amplified by PCR using Illumina primers (the cycle number ranged from 8 to 12) and then indexed in a second round of PCR using Nextera dual index primers, followed by clean up with AMPure XP beads (Beckman Coulter). The samples were ...
The beads were resuspended in 50 μl of the following PCR master mix with indexed primers from the Nextera DNA Sample Preparation Index Kit (Illumina, FC-121-1011): Phusion HF 2× (NEB, M0531L) 25 µl, Nextera Index 1 (N7XX 5.5 μM) 1 µl (1.5 for Hi-C), ...
Finally, duplicate reads were marked (java -jar picard.jar MarkDuplicates -I input.bam -O output.bam -M metrics.txt -REMOVE_DUPLICATES true -ASSUME_SORT_ORDER coordinate) and the BAM file was indexed (bamtools index -in input.bam). Variant discovery was performed using the Genome Analysis To...
